Session 5A Atmospheric Composition and Modeling—Part II

Tuesday, 9 January 2018: 10:30 AM-12:00 PM
Room 18CD (ACC) (Austin, Texas)
Host: 20th Conference on Atmospheric Chemistry
Richard S. Eckman, NASA/LARC, Hampton, VA and Kenneth W. Jucks, NASA Headquarters, Science Mission Directorate, Washington, DC

This session welcomes studies funded by, but not limited to, NASA’s Atmospheric Composition Modeling and Analysis Program (ACMAP) and Aura Science Team (AST). In particular, studies related to global and regional modeling and/or satellite data analysis in the areas of atmospheric chemistry, air quality, and the oxidation efficiency in the troposphere, stratospheric chemistry, and ozone depletion, and interactions between atmospheric chemistry, weather, and the climate are welcome. Studies of long-term trends in atmospheric composition are also of interest, where the connection between cause and effect is elucidated using models. The session is also interested in studies that integrate observations from NASA instruments with models to address attribution and predictions. Use of satellite and suborbital datasets and ground-based measurements are encouraged for modeling constraints and verification where applicable.
