AB: The South Asian monsoon circulation has a strong influence on upper troposphere - lower stratosphere (UTLS) transport during NH summer. We are using AIRS water vapor and ozone retrievals to study climatology and variability of the monsoon region, and making detailed comparisons to chemical transport model (CTM) simulations (using MOZART). Climatological comparisons (based on 2 years of AIRS data) show enhanced water vapor and reduced ozone in the UTLS monsoon region, in reasonable agreement with MOZART results. Studies of daily, synoptic variability are focused on quantifying the influence of monsoon 'eddy-shedding' events in the UTLS.
