Evaluation of the Cloud Fields in the UK Met Office HadGEM3-UKCA Model Using the CCCM Satellite Data Product to Advance Our Understanding of the Influence of Clouds on Tropospheric Composition and Chemistry

To determine the role of clouds in driving inter-annual and inter-seasonal variability of trace gases in the troposphere and lower stratosphere with a particular focus on the importance of cloud modification of photolysis. To evaluate the cloud fields and their vertical distribution in the HadGEM3 model utilizing CCCM, a unique 3-D cloud data product merged from multiple A-Train satellites (CERES, CloudSat, CALIPSO, and MODIS) developed at the NASA Langley Research Center.

Three-Position Cryogenic Actuator

Linear actuator set at one of three positions by supplying gas at suitable pressure. Designed for use as part of relief valve in system storing liquid oxygen. Stops at any of three positions, depending on pressure at supply port. Seals made of polytetrafluorethylene for low friction at low temperatures. Use of polytetrafluoroethylene and large clearances reduces friction and makes possible operating over range of temperatures from -420 to 250 degree F (-251 to 121 degree C).
