abstract = {The Asian Tropopause Aerosol Layer (ATAL) in the Northern
Hemisphere during summer was first discovered in satellite
observation of aerosol particles in the Upper Troposphere /
Lower Stratosphere (UTLS) by Vernier et al. (2011; 2015). It
is related to the Asian monsoon anticyclonic circulation at
UTLS altitudes. Motivated by the current lack of detailed
understanding of the origin of ATAL particles and the
transport of aerosols from the Asian monsoon anticyclone
into the extratropical UTLS, we propose a model study based
on simulations with the three-dimensional chemical transport
model CLaMS. Simulations will be performed for the Asian
summer monsoon 2017. In the framework of the StratoClim
project, an aircraft measurement campaign was conducted in
Kathmandu (Nepal) in summer 2017. A variety of trace gases
and aerosol characteristics have been measured for the first
time in the Asian monsoon anticyclone up to 20 km altitude.
By using artificial tracers of air mass origin (Vogel et
al., 2015; 2016; 2019), we plan to analyze the transport of
aerosol particles into the extratropical UTLS with the help
of the new ERA-5 reanalysis data from ECMWF.},
