Session 7C Atmospheric Composition Modeling and Analysis Program (ACMAP) I

Tuesday, 14 January 2025: 1:45 PM-3:00 PM
226 (New Orleans Ernest N. Morial Convention Center)
Host: 27th Conference on Atmospheric Chemistry
Chair:
Richard S. Eckman, NASA, Langley Research Center, Hampton, VA
Cochairs:
Kenneth W. Jucks, NASA GSFC, Laboratory for Atmospheric and Space Physics, Greenbelt, MD; Henry Selkirk; Barry L. Lefer, NASA, Earth Science Division, Washington, DC and Jun Wang, the university of Iowa, Iowa City, IA

This session welcomes studies funded by, but not limited to, NASA’s Atmospheric Composition Modeling and Analysis Program (ACMAP) and Aura Science Team research programs. In particular, studies related to global and regional modeling and/or data analysis in the area of atmospheric chemistry, air quality, and the oxidation efficiency in the troposphere, stratospheric chemistry and ozone depletion, and interactions between atmospheric chemistry 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 also welcomes studies that integrate observations with models to address attribution and predictions. The use of satellite observations, suborbital data sets, and ground-based measurements are encouraged for modeling constraints and verification where applicable.
