      abstract     = {During the StratoClim Geophysica campaign, air with total
                      water mixing ratios up to 200 ppmv and ozone up to
                      250 ppbv was observed within the Asian summer monsoon
                      anticyclone up to 1.7 km above the local cold-point
                      tropopause (CPT). To investigate the temporal evolution of
                      enhanced water vapor being transported into the
                      stratosphere, we conduct forward trajectory simulations
                      using both a microphysical and an idealized freeze-drying
                      model. The models are initialized at the measurement
                      locations and the evolution of water vapor and ice is
                      compared with satellite observations of MLS and CALIPSO. Our
                      results show that these extremely high water vapor values
                      observed above the CPT are very likely to undergo
                      significant further freeze-drying due to experiencing
                      extremely cold temperatures while circulating in the
                      anticyclonic “dehydration carousel”. We also use the
                      Lagrangian dry point (LDP) of the merged back-and-forward
                      trajectories to reconstruct the water vapor fields. The
                      results show that the extremely high water vapor mixed with
                      the stratospheric air has a negligible impact on the overall
                      water vapor budget. The LDP mixing ratios are a better proxy
                      for the large-scale water vapor distributions in the
                      stratosphere during this period.},
