Adaptive Reference Spectrum-Based Spectral and Radiometric Calibration of GF-5B GMI Using Physics-Based Radiative Transfer Simulation

Accurate spectral and radiometric calibration is essential for reliable greenhouse gas retrieval from satellite hyperspectral observations. However, long-term in-orbit operation may introduce wavelength shifts and radiometric response inconsistencies, particularly within narrow atmospheric absorption bands, reducing th...
