Atmospheric Composition and Air Quality
GFDL scientists aim to advance our understanding of earth’s past, present, and future atmospheric composition and climate. We develop sophisticated computer models representing the emissions, transport, chemical transformations, and sinks of trace gases and aerosols throughout the troposphere and stratosphere. Concentrations simulated by these models are evaluated using in situ and remote sensing observations. We attempt to advance the understanding of the impacts of atmospheric trace gases and aerosols on climate, surface air quality, ecosystems, and UV radiation fluxes.
