EUMETSAT has initiated routine inter-calibration of the infrared channels of Meteosat imagers and the Infrared Atmospheric Sounding Interferometer (IASI) on Metop-A, based on the regression of collocated radiance observations, weighted according to their spatial variability. This paper describes the algorithm and presents key results for Meteosat-7, -8 and -9 during 2007. These demonstrate the ...

This paper addresses the conversion of narrow-to-broadband radiances in the special case of the sensor SEVIRI onboard the satellite Meteosat-8 of the Meteosat Second Generation (MSG). The advent of this new program poses the problem of the transfer of operational procedures from the previous satellite Meteosat-7 to MSG. Among these operational procedures are several different implementations of...

ERB(Earth Radiation Budget) data describe how the earth gains en-gergy, due to absorbed solar radiation ux, or looses energy, due to emitted thermal radiation ux. Since the atmospheric energetics is described by diierential equations with derivatives in space and in time, high resolution spatial and temporal ERB data should be available. ERB data derived from satellite measurements exist (ERBE(...

Abstract. The relationship between geostationary radiances and ice water path (IWP) is complex, traditional retrieval approaches are not optimal. This work applies machine learning to improve the IWP from Meteosat-9 observations, with a focus on low latitudes, training models against retrievals based CloudSat. Advantages of include avoiding explicit physical assumptions data, an efficient use i...

The geometric accuracy of the images acquired by the SEVIRI (Spinning Enhanced Visible and InfraRed Imager) instrument aboard the European geostationary satellites Meteosat-8 (formerly MSG-1) and Meteosat-9 (formerly MSG-2) has been investigated in this study. Level 1.5 image data of the High-Resolution Visible (HRV) band with 1-km Ground Sample Distance (GSD) and several multispectral (MS) ban...

The European Organization for the Exploitation of Meteorological Satellites’ (EUMETSAT) Meteosat satellites provide the unique opportunity to compile a 30+ year land surface temperature (LST) climate data record. Since the Meteosat instrument on-board Meteosat 2–7 is equipped with a single thermal channel, single-channel LST retrieval algorithms are used to ensure consistency across Meteosat sa...

The purpose of this work is to express emissivity in Meteosat-8/SEVIRI channels by means of linear combinations of LSE values in the thermal bands of MODIS sensor. Then, the developed linear models are applied to MODIS11C3 monthly CMG LST product in order to obtain LSE estimations for SEVIRI channels within Meteosat-8 disk. PALAVRAS-CHAVE: Emissivity; Meteosat-8; MODIS. RESUMO. O objetivo deste...

Geometric cloud height estimation provides an alternative to cloud top temperature methods if two satellites view the same cloud. First we demonstrate the stereo cloud height derivation with a combination of Meteosat 7 and Meteosat 5 5 km resolution Infrared data. Comparison with the temperature technique shows consistency in the majority of the clouds, but some differences. This demonstrates t...
