Veerabhadran Ramanathan, Ph.D.

Distinguished Professor
Applied Ocean Sciences & Atmospheric Sciences

Dr. Ramanathan discovered the greenhouse effect of CFCs (cholorofluorocarbons; belongs to family of halocarbons) in 1975 and showed that a ton each of CFC-11 and CFC-12 has more global warming effect than 10,000 tons of CO2. This discovery established the now accepted fact that non-CO2 gases are a major contributor to planet warming and also enabled the Montreal protocol to become the first successful climate mitigation policy. He led a NASA study with its climate satellite to show that clouds had a net cooling effect on the planet and quantified the radiation interactions with water vapor and its amplification of the CO2 warming. He led international field campaigns, developed unmanned aircraft platforms for tracking brown cloud pollution worldwide. His work has led to numerous policies including the formation of the Climate and Clean Air Coalition by the United Nations. He was honored as the science advisor to Pope Francis' holy see delegation to the historic 2015 Paris Climate Summit and was named the UN Climate Champion in 2013. He has been elected to the US National Academy and the Royal Swedish Academy which awards the Nobel prizes, Foreign Policy named him a thought leader in 2014, and in 2018 he was named the Tang Laureat for sustainability science. 

Shang-Ping Xie, Ph.D.

Climate, Atmospheric Science & Physical Oceanography

Shang-Ping Xie's research centers on ocean-atmosphere interactions and their role in climate formation, variability, and change. The ocean's importance for climate is evident from the facts that most of solar radiation absorption occurs at the Earth's surface and that the ocean occupies seventy percent of the Earth's surface. His research contributes to answering such fundamental questions as what determines the spatial distributions of climate, why it varies in time, how preferred patterns of climate variability form, and how predictable climate is. 
He carries out both diagnostic and modeling studies, using observations and numerical models of the ocean, atmosphere, and their coupled system. Geographically, his work covers all three major oceans of the Pacific, Atlantic, and Indian, and monsoons of Asia, Africa, and the Americas. His research has led to the formulation of wind-evaporation-sea surface temperature (WES) feedback mechanism and the Indian Ocean capacitor effect, the "warmer-get-wetter" idea for rainfall change in global warming, and the discovery of what Science magazine called the longest island wake of the world. 

Ralph Keeling, Ph.D.


Ralph Keeling is a Professor of Geochemistry in the Geosciences Research Division of Scripps Institution of Oceanography, UC San Diego. His research focuses on atmospheric composition, the carbon cycle, and climate change. He is considered a leading investigator of the global oxygen cycle for his precise measurements and analysis techniques. Keeling developed his method for measuring atmospheric oxygen levels utilizing interferometry techniques in the laboratory. He began pioneering measurements of changes in atmospheric oxygen levels from air samples collected at stations around the world. The measurements continue at nine sampling stations, extending from Ellesmere Island in northern Canada over the equator to two Antarctic stations. He also continues the CO2 measurement program initiated by his father Charles D. Keeling. 

Peter Franks, Ph.D.

Biological Oceanography

Peter Franks is a professor of biological oceanography in the Integrative Oceanography Division at Scripps Institution of Oceanography, University of California, San Diego. His research interests include red tides, phytoplankton ecology, and computer modeling of the interaction of physical and biological processes in the ocean. Franks studies recurrent red tides, particularly in the Gulf of Maine. Blooms of a toxic phytoplankton have been appearing each year in the region, forcing the closure of shellfish beds along the coasts of southern Maine, New Hampshire, and Massachusetts. After conducting extensive field studies and analyzing historical data, Franks determined that the toxic cells were transported along the coast in a freshwater plume originating from the Androscoggin and Kennebec rivers. He has developed computer models to understand the details of the transport mechanisms and to locate the source populations. His main interests lie in the study of physical/biological interactions in plankton. In one project, Franks studied how thin layers of phytoplankton form beneath the ocean surface. These microscopic patches of plant life are believed to provide a vital source of food for zooplankton, tiny animals that form a key link in the marine food chain.

Ian Eisenman, Ph.D.

Researcher and Professor
Climate, Atmospheric Science, and Physical Oceanography

Ian Eisenman is an associate professor of Climate, Atmospheric Sciences, and Physical Oceanography at Scripps Institution of Oceanography, UC San Diego. He received a bachelor's degree in Philosophy and Physics from Williams College, a masters degree in Physics from UC Santa Barbara, a masters degree in Applied Mathematics from Harvard University, and a PhD in Earth and Planetary Sciences from Harvard University, followed by a postdoctoral appointment jointly at Caltech and University of Washington. His research focuses on climate dynamics, including sea ice, paleoclimate, icebergs, and the large-scale circulations of the ocean and atmosphere. He uses a variety of models ranging from idealized mathematical representations of climate phenomena that can be addressed with pencil and paper to comprehensive climate models that are run on supercomputers, also drawing on observations. A general theme of much his research is the use of physical modeling and mathematical methods to address questions related to societally relevant problems.

Kimberly Prather, Ph.D.

Distinguished Professor
Climate, Atmospheric Science & Physical Oceanography

Dr. Kim Prather is a Distinguished Professor and the Distinguished Chair in Atmospheric Chemistry at Scripps Institution of Oceanography and the Department of Chemistry and Biochemistry at UC San Diego. Prather's research focuses on understanding the impact of atmospheric aerosols on clouds, human health, and climate. Early in her career, she developed a technique known as aerosol time-of-flight mass spectrometry that is widely used in atmospheric field studies around the world to determine the origin and chemistry of aerosols. Her research involves making measurements of atmospheric aerosol chemistry and developing and using new analytical methods for these measurements. Aerosols occur in the environment in a variety of forms: clouds of ice or water droplets, salt particles from ocean spray, and smoke from a variety of combustion sources. They play an enormous role in our daily lives from affecting visibility and global climate change to endangering our health. Due to applications in research, medicine, and industry, there is great scientific interest in aerosols, however relative to their gas phase counterparts, limited information exists regarding their complex chemistry. Additionally, she has been heavily involved in promoting diversity and increasing participation by under-represented groups both within UC San Diego, as well as outside of the University. 

Marty Ralph, Ph.D.

Climate, Atmospheric Science & Physical Oceanography

Dr. Martin Ralph is a synoptic and mesoscale research meteorologist focused on understanding the physical processes that create extremes in precipitation renging from flood to drought, and on advancing associated observations, predictions, climate projections, and decisions support tools. A major goal through his career has been to better understand, monitor, and predict key elements of the global water cycle including water vapor transport, precipitation and runoff. Scientific understanding of atmospheric rivers, which are critical to both the global water cycle and to the distribution of precipitation and flooding in key parts of the world, is a major thrust. Using these results to evaluate and improve short-term precipitation forecasting and to provide reliable regional climate projections of flooding and water supplies in several areas of the world, are desired outcomes. The application of these findings to key users of weather and climate information on extreme events in the Western U.S. is being developed through new observing strategies, modeling, and the creation of decision support tools tailored to user needs.
