Univ. Colorado at Boulder                                                       Title:  Polar Mesospheric Clouds and Their Atmospheric                                     Environment                                                                                                                                                                                                                                  The polar mesospheric clouds are created at heights near                85km by water vapor condensation onto ice particles.  They are                  sometimes visible in midsummer at high latitudes as "Noctilucent                Clouds"  NSF has supported since 1983 the analysis of data on                   these clouds obtained by Dr Thomas and his team from the Solar                  Mesosphere Explorer satellite.                                                          This continuation proposal is to study the seasonal,                    latitudinal and north/south variability of cloud properties, in                 comparison with a model which includes the microphysics of                      nucleation.                                                                             The proposed work is important for extending our                        understanding of the physics involved in polar mesospheric                      clouds, and also of the vertical and wave motions in the summer                 polar mesospheres, and of the differences between the Antarctic                 and Arctic mesospheres.  The PI and his associates are well                     qualified to carry out the research, and their collaboration with               others will enhance the results.
