Cross-Calibration of FY-3A/VIRR Thermal Infrared Channel with TERRA/MODIS
Considering the limited calibration accuracy of FY-3A/VIRR sensor, and limited opportunities for calibration, the cross-calibration method of infrared channel of VIRR with high-precision MODIS of the onboard polar-orbit satellite TERRA is introduced. The cross-calibration is implemented by using the satellite data in January, March and September of 2013. The results show that the brightness temperature of VIRR calculated by using cross-calibration coefficients is nearly equal to the observed value of MODIS, and the vast majority of brightness temperature bias is less than 1 K. The validation results showed that cross-calibration coefficients has universality.
