MACPEX Planning Meeting, Houston, TX, 2-3 February 2011 NASA LaRC Satellite Cloud Remote Sensing & Field Mission/Satellite Support Patrick Minnis, Louis Nguyen, Rabi Palikonda, Douglas Spangenberg, Thad Chee, J. Kirk Ayers, C. Yost MACPEX Planning Meeting, Houston, TX, 2-3 February 2011 Satellite Support for MACPEX MACPEX Planning Meeting, Houston, TX, 2-3 February 2011 OBJECTIVE Provide near-real time satellite and weather analysis support to the experiment on workstations at the MACPEX field headquarters (FHQ) and through the world wide web. Construct comprehensive cloud and radiative property datasets over a specified domain and over flight areas outside the domain for the duration of the experiment. Reanalzye all satellite data after the field phase to provide reliable data for scientific studies. Perform initial comparisons with in situ, active remote sensing, and other passive retrievals for purposes of satellite validation.

Reduces latency time. - McIDAS software used to ingest data and display the imagery. - about 300 Mb of data download per hour. - requires port 112 to be open to ingest real-time satellite and NWP model data from McIDAS servers (SSEC). - Two person team. One member on-site during up-hours to provide additional data and image-weather data overlays as required. Another will either be at the FHQ or on call.
