Greenhouse Gases and Carbon Cycle Feedbacks
Changes in Surface Radiation, Clouds, and Aerosols
Recovery of Stratospheric Ozone

Measurements and modeling of the distributions of greenhouse gases, providing constraints to our understanding of the global carbon cycle.

Quantifying the distributions and magnitudes of the sources and sinks for important ozone-depleting and greenhouse gases.

Research on the Earth's surface radiation budget and the climate-forcing properties of aerosol particles.

Research on the depletion of the stratospheric ozone layer and the role of ozone and water vapor in forcing climate change.
