Radiometric Cross-Calibration of GF-6 PMS/WFV Using a TOA Reflectance Model Over the Dunhuang Site
Radiometric calibration is essential for quantitative remote sensing, and pseudo-invariant calibration sites (PICSs) provide an effective means for vicarious calibration without in situ measurements. This letter presents a comprehensive top-of-atmosphere (TOA) reflectance model for the Dunhuang PICS using five years (2...
