Long-term cross calibration of HJ-1A CCD1 and Terra MODIS reflective solar bands

Scientific Reports, 2021
Since its launch on September 6, 2008, HJ-1A has been in the orbit for 13 years. The CCD1 sensor on the HJ-1A has four reflected solar bands. Since the calibration frequency is limited to the annual site calibration, cross-calibration is an effective ...
