Atmospheric Composition

The upper troposphere (UT) is a key region for understanding tropospheric and stratospheric chemistry, climate change, and the coupling between chemistry and climate. Thus, it is important to understand the controls on the composition in this region. We propose here to use measurements from several different instruments (including the AIRS and MLS satellite instruments) together with models to examine the distributions and variability of trace gases (in particular, water vapor and ozone) in the upper troposphere.
The spatial and temporal variations of tracer PDFs will be examined using observations, simulated fields, and statistical models, and variations will be linked to different transport processes. We will also attempt to link this transport to dynamical processes, which will be important for understanding how the transport, and hence composition, may be altered by changes in the climate.

This research directly addresses one of the specific goals of the solicitation as it uses observations from multiple instruments together with models to address outstanding questions about atmospheric composition. Specifically it will improve our understanding of the distributions of upper tropospheric water vapor and ozone, the role of transport, and possible impact of climate change.
