Title: Radiometric Cross-calibration of the FY1D/VIRR and EOS/MODIS in the Visible and Near-infrared Spectral Bands

First, the match bands of the two sensors were obtained. Then the 6S code was run to calculate their band match factor, and the apparent radiance and reflectance of the FY1D/VIRR were gained according to the digital numbers of the EOS/MODIS when the satellite over passed the Dunhuang Radiometric Calibration Site, onboard calibration results and match factors. After comparing the apparent radiance and reflectance to the digital numbers of the FY1D/VIRR when FY1D over passed the Dunhuang Radiometric Calibration Site at the same time, the calibration coefficients were obtained. The consistency between the results of this cross-calibration and those of site test was good. The method could be used to validate the pre-launch calibration results.Read More
