18 November 2014 GOSAT TANSO FTS TIR band calibration: a five year review
Author Affiliations +
The GOSAT thermal infrared (TIR) band calibration is reviewed for the five-year time period from April 2009 through March 2014. Pre-launch characterization has been augmented by post-launch analysis of on-orbit data and comparison with coincident measurements from other satellite, airborne, and ground-based sensors. Successive refinements of the TIR band ground-processing software have incorporated corrections for detector non-linearity and polarization. Estimates of radiometric uncertainty have also been made. The comparison of GOSAT TIR band nadir and off-nadir comparisons (SNOs and SONOs) provide a quantitative spectral assessment of the radiometric bias relative to the NASA AIRS and EUMETSAT IASI sensors.
