Abstract
We present our study on the sub-seasonal variability of UTLS aerosols and CO that is a result of
the variability induced by the sub-seasonal variability of the Asian summer monsoon dynamics.
We use the NASA global model GEOS simulations that incorporates emissions from
anthropogenic, biomass burning, volcanic, and other natural sources to simulate CO, aerosols and
related gases and the model experiments separating source types (anthropogenic, biomass
burning, volcanic) and source locations (East Asia, South Asia). With model results and
observations from recent aircraft measurements (StratoClim, ACCLIP) in the UTLS over the Asian
summer monsoon regions, we will discuss (1) the sub-seasonal variability of transport pathways of
surface-generated pollutants to reach UTLS, and (2) sub-seasonal variation of aerosol composition
that is determined by the variability of source type originating in different locations
