  1. 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

  2. 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.

  7. International MODIS/AIRS Processing Package Goal: Transform direct broadcast Level-0 data (MODIS/AIRS/AMSU/HSB) to calibrated & geolocated radiances (Level-1B).

  8. International MODIS/AIRS Processing Package • Goal: • Transform direct broadcast Level-0 data (MODIS/AIRS/AMSU/HSB) to calibrated & geolocated radiances (Level-1B). • IMAPP Features: • Ported to a range of platforms (IRIX, SunOS, AIX, HPUX, Linux), • Only tool kit required is NCSA HDF 4.1r3, • Processing environment is greatly simplified, • Downlinked or definitive ephemeris/attitude data may be used, • Passes of arbitrary size may be processed, • Available at no cost; licensed under GNU GPL. • Available from: • http://cimss.ssec.wisc.edu/~gumley/IMAPP/
