摘要: This study aims to evaluate quantitatively the land surface temperature (LST) from SEVIRI data (Spinning Enhanced Visible and Infrared Imager, onboard MSG-2 satellite) with MODIS (Moderate Resolution Imaging Spectroradiometer, Terra)-derived LST extracted MOD11B1 V5 product. Two SEVIRI-derived level-2 products are used for this purpose: LSTs retrieved using generalised split-window method emissivities estimated day/night TISI (Temperature Independent Spectral Indices)-based generated by Land Surface Analysis of Satellite Application Facility. The results show that (1) higher discrepancies observed during daytime, especially bare areas, a maximum 5.7 K; (2) these differences time- cover-dependent; (3) strongly depend on view zenith angle differences; (4) two retrieval algorithms present discrepancy difference 6.1 K.
