RESEARCH BACKGROUND (revised on 27 April 2022):
After completing my Bachelor of Science degree in physics from the University of the Philippines in 1962, I was among the first to be hired as a junior scientist at the then newly established Philippine Atomic Research Center. The job provided my first exposure to a scientific research environment and was delighted to do some work with Dr. Querino Navarro on neutron diffraction scattering. It was my first opportunity to do serious scientific research and although I enjoyed the experience, I started feeling that I was not mature enough to address the challenges of science research. A few months later, I took advantage of an offer from Dr. M. Magno, who was then head of the physics department at UP, for a position as an instructor in physics at the University of the Philippines. The teaching job and the interactions with students was great but I soon realized that I needed a more advanced education to be an effective member of a faculty in what is supposed to be a research university. I applied for graduate studies in the US and in 1964 and I was fortunate to get admission at Florida State University where I finished my masters degree in physics in 1966. At Florida I did research in experimental particle physics with Dr. John Albright and Dr. Lannutti and did a thesis on "3-prong events from K-meson interactions on deuterium," using bubble chamber data. It was an exciting field at that time with new breakthroughs reported more often than expected. I went to UCLA in 1966 where I pursued the same field of research and did a thesis on "Inverse Pion Photoproduction and Time Reversal Invariance in Electromagnetic Interactions," under the supervision of Drs. Ben Nefkens and Roy Haddock. This work, which was done using the 184" synchro-cyclotron at the Lawrence Berkeley Laboratory, addressed one of the key issues in symmetry conservation laws called CPT (Change Conjugation, Parity and Time Reversal). There were previous discoveries of violations in C and P that led to Nobel Prizes so a violation in T would be a big discovery. Unfortunately, our results firmly established that there is no violation in time reversal invariance. I graduated with a Ph. D. in physics in 1972 and worked as a research associate in physics first at UCLA and then at the University of Virginia. At the University of Virginia, I conducted with Prof. K. Ziock and others, several pion-capture experiments that provided new insights into nucleon charge exchange processes. The major facilities used were the then newly constructed Los Alamos Meson Facility and NASA's Space Radiation Effects Laboratory in Virginia. A special research project using the facilities of the nuclear engineering laboratory at the University of Virginia also led to a co-discovery (with Prof. Ziock) of a unique unfolding technique for measuring the stopping power of nucleons.
In 1977, I started looking for a permanent job and was informed about new climate change programs at NASA by Berkeley physics friends and was introduced to satellite remote sensing techniques for Earth science studies. I joined the Computer Sciences Corporation as a senior analyst and did contract work with NASA where I became involved with analysis of aircraft infrared data used to test ability to measure sea surface temperature (SST) using infrared sensors. After six months I basically completed the SST work and started doing remote sensing studies of sea ice using data from a satellite microwave sensor. The principal investigator of the project and the NASA connection was Dr. Jay Zwally. At this point, I felt sad that I am moving away from basic physics which is the core of my training but after working with Dr. Zwally for a few months I get to realize that the field is quite interesting and that I was making a significant contribution. The detectors are similar to those used in particle physics and from a perspective of about 1000 km high from the Earth I realized that these tools and techniques will revolutionize our way of studying the Earth's climate and environmental system. With the encouragement of Dr. Zwally, I applied to be a physical scientist at Goddard Space Flight Center, which was then beginning to be a world's center for Earth science studies. I became a staff member at Goddard in 1979 and almost right away I was asked to assume a key role in the production of the first atlases on the sea ice cover as observed by the Electrically Scanniing Microwave Radiometer (ESMR), which was a one-channel imaging system at horizontal polarization. The first atlas was for the Antarctic region and published in 1983 while the second atlas was for the Arctic and published in 1987.
While the atlas work was going on, I started getting interested in some polar processes that can be observed from satellites. Sea ice is a key component of the Earth's climate system and is expected to provide early signals of a potential change in climate. The polar regions are among the key regions for climate change studies because of the expected amplification of the global warming signal primarily due to ice-albedo-feedback effects. For example, sea ice is an efficient reflector of solar energy and a decline in the sea ice cover would cause more solar heat energy to be absorbed by the ice free ocean (which is not a good reflector of solar energy) that will in turn cause more surface warming and further melt in the sea ice. A study with Dr. J. Zwally on the emissivity of the Antarctic and Greenland ice sheet, using a radiative transfer model for firn (old snow), led to the confirmation of the large dependence of the microwave emissivity (brightness temperatures) of the ice sheet to snow granularity. We also did a study (with Dr. Parkinson) on the variability of the Antarctic sea ice extent and refuted a previous Science article that claimed the coming of an ice age using Antarctic sea ice cover data.
The use of the one-channel ESMR data was limited but enabled a good evaluation of large scale characteristics of the sea ice cover. It also led to the discovery of some important phenomenon like the occurrences of large Weddell Polynyas in 1984, 1985 and 1986 and the extent and variability of the Odden which is one of the only 4 sites of a deep ocean convection globally. The advent of multichannel systems (e.g., SMMR) was intriguing because it provided the means to learn more about sea ice and make assessments more accurately. To get myself started, I made a comprehensive study of the multichannel microwave emissivity of sea ice through the use of co-registered thermal infrared and passive microwave data. The cluster analysis of the resulting multichannel emissivity data produced surprising valuable results including the existence of radiometrically difference ice surfaces and provided the motivations for in situ surface studies. I participated in the first winter cruise in the Antarctic with the key goal to better understand the strange Weddell Polynya phenomenon. At the same time, as a NASA principal investigator, I jointly made measurements with Drs. Tom Grenfell of the University of Washington and Al Lohanick of AWL Research Inc. of microwave emissivities of sea ice, using sensors mounted either on a ship's rail or a sled, to better understand what causes the variability in the emissivity of sea ice. These experiments showed that the Antarctic sea ice emissivity varies with ice type, thickness, snow cover, wetness, and snow cover characteristics.
In 1987, I led a NASA aircraft experiment in the Arctic and was able to successfully overfly a nuclear submarine track within meters and hours at a time when GPS was still being developed for navigation. One of the key results from this project, which was done jointly with Prof. Peter Wadhams of the University of Cambridge and others, is that the thickness distribution of sea ice can be inferred from laser measurements of the surface freeboard thickness of the sea ice cover. This technique was endorsed by NOAA as a potentially valuable tool for detecting ice thickness and climate change. The results were used in part to justify the development of new altimeter systems like the ICESat1, ICESat2 and CryoSat2. The sensitivities of SAR and passive microwave data to thickness and other surface properties of sea ice were also analyzed and quantified. Furthermore, the aircraft data confirmed the large spatial variability in the emissivity of multiyear ice as revealed previously by the aforementioned cluster studies on emissivity.
In 1984, I developed the Bootstrap Algorithm for deriving sea ice parameters from multichannel passive microwave data. This technique which allows the retrieval of sea ice parameters even without explicitly modeling atmospheric effects has been validated and shown to provide more accurate results than other algorithms in the Antarctic and the seasonal regions of the Arctic. It is also one of two techniques used by the University of Colorado Polar Data Center to derive ice concentrations that are distributed to the scientific public in CD-ROM format while a newly enhanced version, that takes advantage of the capabilities of the new system, will be used for deriving ice products from the EOS-AMSR data. Just recently, it was also chosen by JAXA of Japan as the algorithm for generating standard ice products from the ADEOS2-AMSR data and GCOM/AMSR2. I also discovered that the best way to quantify the perennial sea ice cover in the entire Arctic region is through the use of end of summer data. Research on summer ice with Dr. R. Kwok of JPL also provided new insights into melt effects, the areal coverage of meltponding, and the actual mass of ice that survives the summer.
Many of the important processes in the polar regions occur in polynya regions and at the marginal ice zones (including the Odden). In these regions, the vertical fluxes of heat, humidity and salinity are very intense. The importance of polynya studies were highlighted in a Scientific American article co-authored with A. Gordon in 1988. We accidentally discovered in 1987 the existence of a recurring polynya at the Cosmonaut Sea, which have caught the attention of international scientists who have initiated field and modeling programs in the region that continues to this day. A multi-parameter statistical study of polynyas, which was done in collaboration with Prof. R. De Veaux of Princeton in 1993, established that bathymetry has an important role in the formation of polynyas, while a separate paper with Prof. A. Gordon also shows that current-current interactions in involves the Southern Ocean Circumpolar Current can be a big factor. A time series study with S. Jacobs also indicated an extensive retreat of multiyear ice in the Bellingshausen Sea from 1989 through early 1990s. This effect, which could have a profound influence on the oceanography and ecology of the region, is shown to be strongly correlated with the rising surface air temperatures observed in the region. The retreat has been continuing up to early 2000s and the region has been identified as a climatologically anomalous region. It turned out that the most important discovery about sea ice by satellite data is the “Rapidly Declining Arctic Perennial Ice Cover” which I reported in a Geophysical Research Letter (GRL) paper published in 2002. The perennial ice has been around in the Arctic for at least 1,500 years and with the reported decline of about 10% per year it is likely that the Arctic Ocean could become a blue ocean in the summer within a century if the decline rate continues. The paper caught the attention of scientists, environmentalists and politicians worldwide, and was the “Editor’s Choice” by Science Magazine in 2002. It was in covered by newspapers worldwide and a well-known professor from Denmark took his time to write a letter to me admiring the publication and sending me favorable comments from some of the top climatologists in Europe.
Among the key climate parameters in the polar regions is surface temperature which is measured at polar meteorological stations and by buoy sensors. These measurements, however, are sparsely distributed and to provide a better characterization of temperature distributions in the polar regions, I looked into the utilization of satellite infrared data for this purpose. It has not been done previously because of difficulty in discriminating clouds from snow covered surfaces and because of large data volume. I was able to develop a cloud algorithm that works even with a single channel data and with modest NASA support, I generated the first surface temperature maps in the polar regions from Nimbus-7 THIR data and reported results of analysis of the data in a JGR paper in 1994. Encouraged by modelers and other polar scientists, this project was continued using the NOAA-AVHRR data and eventually, I have generated monthly average data covering 1979 through the present. The data reveal predominantly warming trends around the Antarctic region and an anomalously warm event in the Antarctic plateau in 1995. Around the sea ice region, a succession of warm and cold anomalies are also observed that are coherent with retreats and advances of sea ice, respectively. This is consistent with the Antarctic circumpolar wave, except that there is a predominance of mode 3, instead of mode 2 as previously postulated, for the wave. The paper on the Arctic perennial ice was followed by a paper on the "Warming trends in the Arctic," based on AVHRR data that was published in 2003 in the Journal of Climate. The results indicate an acceleration of warming in the Arctic and suggest a considerable vulnerability of the cryosphere that includes the permafrost, snow cover, glaciers and the Greenland ice sheet which has a sea level equivalence of more than 7 meters. The paper was again cited as the "Editor's Choice" by Science Magazine in 2004 and was even more popular than the Arctic perennial ice paper. Realizing the importance of the results, NASA decided to invite world experts in the field to discuss the key issues with me in front of top national and international journalists. The audience included reporters from major US and international newspapers and again, the newspaper and television coverage worldwide was huge.
Sea ice also affects the biology and productivity in the marginal ice zones, where phytoplankton blooms have been observed to be considerably enhanced in spring. In the 1980s, I was approached by Prof. Neal Sullivan, a biologist from the University of Southern California, to collaborate on ice-biology interaction studies and to participate in the AMERIEZ and related studies. A comprehensive study of phytoplankton pigment distribution in the Southern Ocean using available ocean color in conjunction with in-situ measurements were made in collaboration with Drs. C. McClain, W. Smith, K. Arrigo and others. The effort eventually led to several papers including an article published in Science. These studies generated a lot of feedback from readers including numerous requests for data and reprints. A complementary modeling study done with Drs. W. Smith and N. Keene of the University of Tennessee also provided estimates of the biological productivity of the entire Antarctic region using satellite data. Similar studies of phytoplankton distributions in the Arctic and the Greenland Sea regions were also done with Dr. G. Mitchell of Scripps Institution of Oceanography. With the launch of a new color sensor, called SeaWiFS, new efforts were pursued in collaboration with Dr. Glenn Cota of Old Dominion University. Two new papers were published in the process and a third one was under review when Dr. Cota unexpectedly died due to an unusual disease. Despite the setback, the work continues on in collaboration with Dr. Walker Smith and so far 2 other papers on the topic have been published.
Occasionally, I have been asked by book editors to write review articles on remote sensing, sea ice and related studies. I wrote an exhaustive article on "Remote sensing of the Polar Oceans” in 1990 and was author or co-author of several chapters of the AGU 1992 monograph on Microwave Remote Sensing of Sea Ice. I was also the author of the first chapter of the 1994 AGU monograph entitled "Arctic Oceanography: Marginal Ice Zones and Continental Shelves" and a chapter on "Sea Ice Geophysical Parameters from SMMR and SSMI data" which appeared in a 1994 CRC book entitled "Oceanographic Application of Remote Sensing." I just completed a book chapter on “Large scale sea ice characteristics and variability,” published by Blackwell Publishing Inc. in 2002 and completed a book on "Polar Oceans from Space," published by Springer Press in 2010. The last one took a few years to complete but was satisfying in the end because the publisher sold all printed copies and there were thousands of download of the digital version for several years after that.
The overall strategy of my research is to do in depth studies of physical, radiative, and biological processes in the polar regions with special emphasis on finding accurate signals of our changing climate and the determination of fluxes in marginal ice zones, leads, and polynyas to determine how these unique features in the polar regions are affecting our planet. The immediate goal is to use concurrently, time series data of sea ice cover, wind, temperature, ocean color and other geophysical parameters to study interdecadal changes in these variables that may reflect a change in the Earth climate system. Preliminary results already show drastic changes in the Arctic sea ice cover and surface temperature that provide strong a strong signal of changes in our planet. Whether they are caused by global greenhouse warming is another story since we have to depend on modeling studies to get the connection. I have been fortunate to be part of a big NASA project that was originally called the “Mission to Planet Earth.” The key objective is to study the Earth’s Climate system through satellite and modeling studies with the hope that we get to know more accurately how the Earth’s system is affected by human activities. There is only one Earth, or a planet with intelligent life in the entire universe that we know of and the goal is to keep the Earth as livable as it has been for ages. At a time when the US budget was being cut to address economic problems, I was surprised when they announced that the $16B NASA Earth mission proposal was funded. My proposal to develop algorithms for sea ice parameters from the proposed passive microwave sensor was funded as well. It was a proposal I had to write while on a field trip in the Antarctic/Southern Ocean. This entitled me to be a bona-fide member of the mission and a team member and PI of the proposed AMSR sensor.
It took time for the instruments to be put together, the satellites to be built and the data system to be formulated and put together with working software. In December 1999, the first of a series of NASA Facility Instruments called EOS/Terra was launched. This was followed by the launch of EOS/Aqua in May 2002 and by EOS/Aura in 2008. Terra is meant to monitor land, Aqua to monitor the oceans and Aura to monitor the atmosphere but the usefulness of the sensors are not strictly confined to these applications. It was amazing that all these facility instruments were launched successfully and most of the key instruments are still working up to this day. In addition, historical data generated from basically the same type of sensors continued to be accumulated with record lengths exceeding 40 years thus enabling meaningful trend analysis. The advent of new and powerful desktops and cheap data storage disk drives in addition to the available satellite data is exciting and intriguing resulting in the conduction of research that were thought not possible a few years back. I became one of the beneficiaries of such powerful research tools and readily available satellite data and this led to many research accomplishments including the publication of 7 scholarly books, 22 book chapters and more than 140 ISI papers that have been cited in international journals about 30,000 times. In recognition to my efforts, I have received numerous awards including the NASA Exceptional Achievement Medal which is one of the most prestigious award given to a NASA scientist. I am also happy that NASA appreciated my career since I have also been given the NASA/GSFC outstanding career award.

NAST Article about Josefino C. Comiso
Josefino Comiso is a senior scientist at the Cryospheric Sciences Laboratory of the NASA Goddard Space Flight Center. He received his Bachelor of Science degree in Physics from the University of the Philippines and became one of the first junior scientists to work at the Philippine Atomic Research Center where he did research on neutron diffraction. After a few months, he took advantage of a faculty job offer at the University of the Philippines and taught physics as an instructor for a year and a half before attending Florida State University (FSU) where he received a Master of Science degree in Physics. At FSU he did research in experimental particle physics and analyzed bubble chamber data on 3-prong events from K-meson interactions with deuterium nucleus. He then went to UCLA to pursue a Doctor of Philosophy degree in physics and did his thesis project at the high energy accelerator facilities at the then Lawrence Radiation Laboratory at Berkeley, California. He studied inverse pion photo-production to assess possible violation of time reversal invariance in electromagnetic interactions. Time reversal is one of the fundamental symmetries in nature called Charge, Parity and Time Reversal (CPT) and was at that time a very hot topic in physics because of previous observations of a violation of Charge and Parity symmetries. The discovery of a violation of Parity led to the awarding of Nobel Prizes to scientists at Columbia University and the subsequent discovery of a violation in Charge Conjugation let to Nobel Prizes to scientists at the University of Chicago. His results, which were later confirmed by others, indicated that there is no violation of Time Reversal in Electromagnetic Interaction. He did postdoctoral research at the University of Virginia and studied pion-capture in carbon processes using the then newly constructed linear accelerator (called “pion-factory”) at Los Alamos National Laboratory. At UVa he also jointly developed a unique unfolding procedure for measuring the stopping power of charge particles and participated in projects to investigate alpha induced production of light particles using the NASA synchrocyclotron facility at Newport News Virginia.
Because of declining federal budget for particle physics on account of the Vietnam War, he took advantage of new opportunities at NASA Goddard Space Flight Center especially on their growing climate change program. He first started working at NASA indirectly as a Computer Science Corporation senior consultant and shortly after he was hired as a Physical Scientist at their Earth Sciences Directorate that was then involved on studies of climate change processes through the use of satellite remote sensing sensors which were providing global data for the first time. His studies were first focused on processes in the polar regions because these snow-covered regions are expected to provide early signals of climate change due to ice-albedo feedback effects. His research led to new insights into many important processes and events in the region. For example, analyses of satellite data led to the discovery of unexpected formation of a large polynya in the Weddell Sea that persisted in winter for three succeeding years. A polynya is an ice-free water surrounded by sea ice and it was regarded as counter-intuitive to have such a polynya that was larger in size than the state of California to stay unfrozen in winter despite surface air temperatures that are 20 to 30 degrees below 0 ºC. Also, the data revealed the occurrence of persistent polynyas in the coastal areas that turned out to be even more interesting because they cause continuous production of sea ice that absorbs only a fraction of the salt of sea water thus causing the formation of saline and dense bottom water that becomes part of the global thermohaline circulation of the oceans. A similar phenomenon occurs at an ice feature called Odden ice tongue in the Greenland Sea which is adjacent to the site of a rare deep ocean convection. He was also involved in the study of high latitude phytoplankton blooms and their relationships with the melt of sea ice in the spring that causes the formation of low-density layer at the top that is exposed to abundant sunlight and becomes an ideal platform for photosynthesis.
He served as a principal investigator of satellite research projects after he developed unique algorithms for accurately retrieving sea ice and other parameters from satellite data. He put together long-term data sets on sea ice concentration, ice extent and ice area which he used to study the seasonal and interannual variability of the sea ice cover. Such study led to his observation of an important result that indicated that the perennial sea ice cover in the Arctic is declining very rapidly. The result became highly visible and a worldwide concern because of serious implications including a large transformation of the climate and environment of the Arctic and adjacent regions. He also developed an algorithm for surface temperature using thermal infrared data and reported that the rate of increase of surface temperature in the Arctic is about three times that of global rate causing a general warming in the region. This in turn leads to thawing of the permafrost, greening of the tundra, retreat of the snow cover and melt and loss of mass of numerous glaciers in the Northern Hemisphere. An even more serious implication is the possible acceleration in the melt of the Greenland ice sheet which has a sea level equivalence of about 7 meters.
He was the chief scientist in several NASA aircraft missions in both Arctic and Antarctic regions with the primary goal of validating the sea ice algorithm that he developed. The algorithm is now currently used by NASA, JAXA (Japan Aeronautics Agency), ESA (European Space Agency) and others (i.e., India and China) in the development of satellite climate data records. One of these aircraft missions involved flights over a nuclear submarine in the Arctic that allowed near simultaneous measurements of upward looking sonar from the submarine and Lidar altimeter measurements from the aircraft. The results revealed the feasibility of measuring the thickness of sea ice from space which has not been done before. With the launch of ICESat, ICESat2 and CryoSat2, Lidar and microwave altimeter satellite sensors are now being utilized for sea ice thickness studies.
He has been a member of satellite sensor teams that evaluates the type of sensors needed for climate change and earth science studies. He has served as member of the editorial staff of some journals and book publications and of several committees and panels related to scientific and international projects. With the resources that NASA has been providing over the years, he managed to be the author or co-author of 7 books, 20 book chapters and more than 130 refereed journal articles, which have been highly cited in various journals (more than 40,000 times). He was selected to be a contributing author of 2 chapters of the Intergovernmental Panel on Climate change (IPCC 2007) Report that won half the Nobel Peace Prize in 2007. More recently he served as the coordinating lead author of the Cryosphere chapter of the more recent IPCC 2014 report that deals with “State of the Climate 2013: The Physical Scientific Basis.” Also, he has been visiting the Philippines frequently in recent years as a Balik Scientist Program participant and as a visiting scientist and in addition to serving as mentor and consultant of graduate students and post-docs. He was the lead author of a book on “Changing Philippine Climate: Impacts on Agriculture and Natural Resources,” co-authored by local and Filipino-American experts. The book won the NAST Outstanding Book of the Year Award in 2015 and represented the Philippines in a book festival in Europe.
He has been the recipient of several NASA awards, including the NASA Exceptional Achievement in Science Medal (regarded as among the most prestigious awarded given to a NASA scientist), NASA/GSFC Career Achievement Award, a few NASA Group Achievement Awards and several NASA Outstanding Performance Awards. He was also the recipient of the Pan-Ocean Remote Sensing Conference (PORSEC) Outstanding Achievement in Science Award, UPAA Distinguished Achievement Award in Science and Engineering, UPAAA Most Distinguished Alumnus award, Filipinas Magazine Outstanding Achievement in Science and Medicine Award and the Filipino Image Magazine 20-Outstanding Filipino-American. He was one of the 10 cited in the book entitled “Ten Outstanding Filipino Scientists,” by Prof. Qeena Lee-Chua of Ateneo University, selected a Fellow of the Japanese Society for the Promotion of Science in 2006 and elected as a Corresponding Member of the National Academy of Science and Technology in 2016.
