Paper Abstract

The absolute calibration of HJ-1B thermal infrared channel is achieved by 7 times cross-calibration of Qinghai Lake in 2010, between the HJ-1B thermal infrared channel and MODIS 31, 32 channels. At the same time, the intercept of calibration coefficients is calculated. First, the spatial match are completed between the HJ-1B IRS image and MODIS 31, 32 channels image. Then, the spectral response of HJ-1B IRS thermal channel and MODIS 31, 32 channels are used for the spectral match. Based on the SST algorithms of MODIS, the MODTRAN4.0 is used to simulate the radiative transfer results under the condition of variety surface temperature of the Qinghai Lake, the atmospheric profile, observational geometry combined with the spectral response functions of the remote sensors. The quantitative linear relationship can be established with the simulation results. The gain and offset of cross-calibration are 52.7788 1/(W/(m2•sr•μm)), -55.4137. The result needs further validation of longer sequence.
