| 英文摘要 | This paper addresses the cross-calibration of the infrared channels 4 (3.9 μm), 9 (10.8 μm) and 10 (12.0 μm) of the Spinning Enhanced Visible and Infra-Red Imager (SEVIRI) onboard the Meteosat Second Generation 1 (MSG1) satellite with the channels of the MODerate resolution Imaging Spectroradiometer (MODIS) onboard Terra. The cross-calibrations, including the Ray-Matching (RM) method and the Radiative Transfer Modelling (RTM) method, were developed and implemented over a tropical area using SEVIRI and MODIS measurements of July 2005 and July 2006 with absolute view zenith angle differences ( ΔVZA )<0.5°, absolute view azimuth angle differences ( ΔVAA )<0.5° and absolute time differences ( ΔTime )<10 min. The results obtained by the RM and RTM methods revealed calibration discrepancies between the two sensors. The results obtained by the RM method were consistent with previously published results. The results obtained by the RTM method were consistent with the results obtained by the RM method if the temperature differences caused by the spectral differences between the two sensors were taken into account. From the cross-calibration results obtained by the two methods, the use of the results obtained by the RTM method to recalibrate the SEVIRI data is recommended. The recalibrations remove the overestimation of the Land Surface Temperature (LST) retrieved from the SEVIRI data by a split-window method. |
