Radiometric cross-calibration of the SZ3-CMODIS and EOS-MODIS in the visible and near-infrared spectral bands by using two targets in the images

In This work, the radiometric cross-calibration method is adopted to calibrate the SZ3-CMODIS based on the on-board calibration results of EOS-MODIS. The calibration results worked out by cross-calibration method are consistent with the calibration results worked out by reflectance-based and pre-launch method.
