  1. 1. Ground Testing 2. Aircraft Underflights 3. Satellite Intercal How Intercalibration fits into the broader Cal/Val activities at CIMSS High altitude aircraft underflights of Geo and Leo platforms, with emphasis on establishing the accuracy of the high spectral resolution sensors (AIRS on Aqua, IASI on METOP, CrIS on NPP) Geo and Leo sensor Intercal analyses, with emphasis on using the high spectral resolution Leo observations as a benchmark. Radiometric and spectral characterization of the aircraft sensors, with an emphasis on (absolute) accuracy and traceability to NIST.

  2. Sky view AERI SHIS Ground Intercal Aircraft AIRS/Scanning HIS (SHIS) comparison • External blackbody views (ice body, intermediate temperature body) • Radiometric Noise • Uplooking sky view comparison with AERI • Spectral calibration • Spatial Field of view • Blackbody electronics GEO-AIRS IR Window Comparisons

  3. MTSAT-1R (JAMI) IR4 (3.7m) band compared to AIRS JAMI-AIRS(K) Quantifying Improvements through Intercal
