基于敦煌辐射校正场的gf-6/Pms时序绝对辐射定标方法

Key Points

• The analysis achieved absolute radiometric calibration with uncertainty better than 4.15%, enhancing data reliability.
• Calibration occurred during 38 passes of GF-6/PMS over the Dunhuang field from July 2019 to November 2024.
• A degradation model was established for radiometric performance metrics of the sensor across various bands.
• The validation showed mean relative differences of 2.34% to 4.12% against Sentinel-2/MSI, affirming the calibration method's validity.
