Studies dynamics, predictability, and impacts of global climate fluctuations generated by the tropical oceans, such as El Niño and La Niña. Uses numerical models to investigate drivers of past environmental changes inferred from geological archives with the objective of improving predictions of future climate change.
Investigation of kinematic and microphysical processes relevant for cloud formation and change of precipitation; conduct modeling, analysis and field studies in cloud physics
Cloud and aerosol processes and their influence on the coupled climate system, recent and projected Arctic sea ice loss, climate model evaluation and improvement using data assimilation and satellite observations, and communicating climate science
Atmospheric and surface remote sensing. Radiative energy budget studies from aircraft, space, and from the ground. Development of aircraft measurement strategies and instrumentation. Quantify cloud, aerosol, and gas radiative effects in different regions of the globe through aircraft/satellite observations and radiative transfer calculations.
Observations of aerosols and trace gases in Earth's atmosphere from the ground to the middle stratosphere. Influences on climate, chemistry, and air quality
Observing clouds from different platforms leading to a greater understanding of cloud physical processes and improving the parameterizations of cloud-related physical processes in climate models
