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.
