AIRSデータに基づいたMODIS地表面温度・放射率プロダクトの検証

抄録

This paper presents a validation of Land surface temperature (LST) product retrieved from Moderate Resolution Imaging Spectroradiometer (MODIS) data. For this purpose we used a scheme which validates LST product indirectly based on the emissivity validation derived from Atmospheric Infrared Sounder (AIRS). In addition we also made LST and emissivity spatial averaging model for compensating the difference of the spacial resolution between sensors. The validation result shows that MODIS LST product involves the emissivity bias of 0.023 and LST bias of -1.3K in Railroad Valley Playa and the emissivity bias of 0.019 and LST bias of -1.8K in Harvard Forest.
