      abstract     = {The impact of different boundary layer source regions in
                      Asia on the chemical composition of the Asian monsoon
                      anticyclone, considering its intraseasonal variability in
                      2012, is analysed by CLaMS simulations using artificial
                      emission tracers. Our simulations show that the Asian
                      monsoon anticyclone is highly variable in location and shape
                      and oscillates between 2 states: first a symmetric
                      anticyclone and second, an asymmetric anticyclone either
                      elongated or split in two smaller anticyclones. A maximum in
                      the distribution of air originating from Indian/Chinese
                      boundary layer sources is usually found in the core of the
                      symmetric anticyclone, in contrast the asymmetric state is
                      characterised by a double peak structure in the horizontal
                      distribution of air originating from India and China. The
                      simulated horizontal distribution of artificial emission
                      tracers for India/China is in agreement with patterns found
                      in satellite measurements of O3 and CO by the Aura Microwave
                      Limb Sounder (MLS). The contribution of different boundary
                      source regions to the Asian monsoon anticyclone strongly
                      depends on its intraseasonal variability and is therefore
                      more complex than hitherto believed, but in general the
                      highest contributions are from North India and Southeast
                      Asia at 380 K. In the early (June to mid-July) and late
                      (mid-August to October) period of the monsoon 2012,
                      contributions of emissions from Southeast Asia are highest
                      and in the intervening period (≈ mid-July to mid-August)
                      emissions from North India have the largest impact. Further,
                      our simulations confirm that the thermal tropopause above
                      the anticyclone constitutes a vertical transport barrier.
                      Enhanced contributions of emission tracers for Asia are
                      found at the northern flank of the Asian monsoon anticyclone
                      between double tropopauses indicating an isentropic
                      transport from the anticyclone into the lowermost
                      stratosphere.},
