In order to simulate the ASTER's thermal infrared sensor that is one of the unique features of the ASTER, a new airborne thermal infrared imaging spectrometer -- airborne ASTER simulator (AAS) -- was planned and manufactured by a Japanese science group. The AAS having unique twenty bands in the TIR region was used for the field experiment in June 1996. Test site was Cuprite, Nevada, U.S.A. The basaltic zone, silicified mountain and playa are typical targets of the flights. The purpose of this experiment was to obtain the high spectral resolution TIR (thermal infrared) data. These data were used for the development and validation of temperature and emissivity separation algorithm. Along the trajectory on the ground, the radiance temperature measurement was synchronized with the AAS flight. ASTER simulation data sets were synthesized from these airborne data, and the performance of temperature and emissivity separation was evaluated by these data.
