Absolute radiometric calibration for thermal infrared bands of FY2B by using NCEP reanalyzed data in Qinhai Lake

摘要

In This work, the NCEP reanalyzed data is used to substitute the atmosphere profile detected by radio sound in Qinhai lake to calibrate the TIR band of FY2B. That the calibration coefficients of FY2B TIR band calculated by using the atmosphere profile of real data and NCEP reanalyzed data are very consistent shows the NCEP reanalyzed data in Qinhai lake can be used to calibrate the TIR bands of satellite sensors.
