In this project we continue our optimization, validation, and integrated analysis of trace gas products retrieved from NASA's Atmospheric InfraRed Sounder (AIRS). Launched in May 2002, AIRS provides an unparalleled view of atmospheric chemistry seeing 70% of the planet each day. At present we are validating version, v5.0.14.0, of the operational AIRS team retrieval algorithm and investigating optimization of existing products as well as the addition of new products for version 6.0. Particular attention will be focused on assessing AIRS CO retrieval performance in the boundary layer with comparison to correlative in situ and remote sensing measurements from ground, air, and space (e.g. continuous ground gas analyzers, aircraft trace gas measurements and whole air samples, AERI and other FTIR trace gas retrievals, and MOPITT and TES satellite retrievals).
