7. AIRS Instrument Suite AIRS, in conjunction with its companion instrument AMSU, provides a unprecedented suite of instruments for weather and climatologically studies –AIRS is a hyperspectral IR spectral photometer 2378 IR channels AIRS also has 4 Visible/NIR channels (8x9 pixels per AIRS spot) –AMSU-A is a MW temperature sounder with 15 channels –Combining Level-1B data from AIRS-suite instruments you can retrieve cloud-cleared IR radiances and physical parameters including: Cloud cover & height Surface temperature & type Profiles of: T, q, trace gasses

9. Climate Studies EOS Satellites primary mission is to understand earth’s climate and identify the causes of climate change. DAAC products are doing just that.

15. Near Real-time Data and Products Direct readout Terra and Aqua data and products have proven useful too. IMAPP (International MODIS/AIRS Processing Package) allows users with X-band receivers to calibrate, geolocate and create science data products in near-real time. Current suite: MODIS data Calibration, geolocation, cloud mask, cloud properties (height, temperature, emissivity, phase), atmospheric profiles (T, q, total precipitable water vapor, stability indices.)

16. EOS Direct Broadcast at SSEC Objective: Routine acquisition and processing of EOS direct broadcast data (NASA HQ funding). Accomplishments: System installed August 5, 2000. 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, atm. profiles, cloud height).

18. International MODIS/AIRS Processing Package Goal: Transform direct broadcast Level-0 data (initially from MODIS) to calibrated & geolocated radiances (Level-1B) and science data products (Level-2). Features: Ported to a range of platforms (IRIX, SunOS, AIX, HPUX, Linux), The only required tool kit is NCSA HDF4, 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/
