WACCM simulated Carbon Monoxide (CO) in the Asian Summer Monsoon anticyclone during 2017 StratoClim campaign at different pressure levels Shawn B. Honomichl, Laura L. Pan, and Marc von Hobe

Short summary
The Asian summer monsoon (ASM) is known to foster transport of polluted tropospheric air into the stratosphere. To test and amend our picture of ASM vertical transport, we analyse distributions of airborne trace gas observations up to 20 km altitude near the main ASM vertical conduit south of the Himalayas. We also show that a new high-resolution version of the global chemistry climate model WACCM is able to reproduce the observations well.
