AB: The University of Wisconsin-Madison Space Science and Engineering Center (UW-SSEC) has developed advanced instrumentation for aircraft platforms for weather and climate applications with an emphasis on absolute radiometric and spectral calibration. The Scanning High-resolution Interferometer Sounder (S-HIS) is a UW-SSEC aircraft instrument that measures upwelling (and down welling) thermal emission between 3.3 and 18 microns at 0.5 cm-1 spectral resolution (unapodized). The measured radiance can be used to obtain temperature and constituent profiles of the Earth's atmosphere and to characterize the infrared properties of the Earth's surface and cloud boundaries. S-HIS observations were obtained from the NASA WB-57 high altitude aircraft based in Houston, Texas during the Aura Validation Experiment in September/October 2004 and June 2005. The S-HIS upwelling and down welling radiance observations are being used in the creation of an aircraft level air temperature product. The Rodgers optimal estimation approach is used to physically retrieve the atmospheric temperature for a vertical profile two kilometers above and below the aircraft. Results will be presented that represent the current state of these measurements and comparisons with other in-situ temperature measurements on board the WB57.
