Session ID#: 27645

Session Description:
Cirrus clouds are the most common atmospheric cloud type. Cirrus formation is induced in a wide variety of dynamical environments, including tropical convection and cold-trapping at the tropopause, orographic and gravity waves and mid-latitude or polar fronts. Large variations in ice particle number density, size distribution, habit and surface smoothness in cirrus clouds make them difficult to parameterize within the radiative and optical models necessary to resolve their impact on climate. This session seeks to relate uncertainties in cirrus cloud microphysical and radiative parameterizations used in atmospheric modeling studies with in situ measurements from balloon and aircraft platforms. Validation of optical properties derived from current ground and satellite-based remote sensors are further encouraged. Sensitivity studies showing the impact of cirrus variability on solar and infrared optical properties in cirrus cloud models, microphysical models used for remote passive sensing retrievals and cirrus cloud process studies are also appropriate for this session.
