Session ID#: 18237

Session Description:
The mesosphere is an important transition zone through which atmospheric disturbances below connect with the thermosphere above.  Also, solar effects play a key role in coupling from above that is manifested by changes in the mesosphere region.  Consequently the mesosphere harbors key information on dynamics, chemistry, long-term atmospheric change, vertical coupling and the role of solar forcing.  Missions such as AIM, TIMED, SNPP, SBUV and AIRS have provided significant advances in space observations of temperature, gases, ice layers, particulates which serve as ice nucleation sites and lower atmosphere dynamics sources. Sophisticated multidimensional models now incorporate new dynamics mechanisms, microphysics calculations and crucial tools to understand coupling between mesopause ice layers and the local environment. We solicit papers discussing the composition, structure and variability of the MLT environment, ice nucleation sources and processes, vertical and meridional coupling, model advances and the extent and causes of long-term changes.
