An A-train and model perspective on the vertical distribution of aerosols and CO in the Northern Hemisphere

[1] We use A-train satellite observations of aerosols and carbon monoxide (CO) (CALIOP, MODIS, and TES) with GEOS-Chem model simulations to analyze long range transport in the Northern Hemisphere over 3 years (December 2006–November 2009), with a focus on the vertical distribution of pollutants. GEOS-Chem underestimates TES observations of CO in all seasons (
