MODIS/AIRS/AMSU/HSB Direct Broadcast & Processing Package at the
Cooperative Institute for Meteorological Satellite Study
Space Science and Engineering Center,
University of Wisconsin-Madison
EOS Direct Broadcast at SSEC
Objective: Routine acquisition and processing of EOS direct broadcast data (NASA HQ funding).
Accomplishments:
• System installed August 5, 2000. As of December 3, 2001 had acquired and archived 1969 Terra MODIS passes.
• Level-1B data and browse images have been produced automatically since January, 2001 and made available via anonymous FTP, DODS server, and Web.
• IMAPP software package for processing MODIS direct broadcast data now in use in USA, UK, Germany, Russia, Japan, China, Korea, Singapore, Australia. Level-2 algorithms (cloud mask, profiles, cloud top height) in early 2002.
