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
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.

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.)
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).

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/
CIMSS Near-Real Time IMAPP automated processing applications: • MODIS L1B and science product validation • Testing of MODIS algorithm product changes • Quick look true-color images for identifying regions of spectral or meteorological interest • Support for field experiments
Example IMAPP Aqua Quicklook Image: Southwest US 19 Aug. 2003
Global Community MODIS IMAPP applications: • MODIS calibration validation over Lake Tahoe, USA. • Providing USA Weather Service forecasters with near real-time high spatial resolution imagery and products (SPORT). • Aiding the Canadian Ice Service in monitoring the amount of ice on Hudson Bay for shipping concerns. • Supplying cloud information from IMAPP as part of the European CLOUDMAP 2 project.
