Correction of the Meteosat-5 and -6 radiometer solar channel spectral response with the Meteosat-7 sensor spectral characteristics
This Letter suggests the substitution of the spectral response of the Meteosat-5 and -6 radiometer solar channel by the one of the Meteosat-7 radiometer. This replacement is motivated by an inaccurate spectral characterisation of the former two radiometers. The impact of this correction on the vicarious calibration of the solar channel is assessed. When the original sensor response is used, a difference of about 20% is found between calibration coefficients derived over sea and bright desert. This difference drops to about 1% when the sensor spectral response of the Meteosat-7 radiometer is used for the calibration of the Meteosat-5 and -6 radiometer solar channel.
