Detection of convective initiation using Meteosat SEVIRI: implementation in and verification with the tracking and nowcasting algorithm Cb-TRAM
In this paper a new detection scheme for convective initiation (CI) under day and night conditions is presented. The new algorithm combines the strengths of two existing methods for detecting CI with geostationary satellite data. It uses the channels of the Spinning Enhanced Visible and Infrared Imager (SEVIRI) onboard Meteosat Second Generation (MSG). For the new algorithm five infrared (IR) c...

متن کاملLand-surface Emissivity Estimation in Meteosat-8/seviri Tir Bands Using Modis Data
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...
متن کاملA new technique for detecting precipitation at mid-latitudes during daytime using Meteosat Second Generation SEVIRI
A new method for the detection of precipitation during daytime using MSG SEVIRI data is proposed. The approach is not only applicable for the detection of mainly convectively induced precipitation by means of the commonly used relation between infrared cloud top temperature and rainfall intensity but enables also the detection of stratiform precipitation (e.g. in connection with mid-latitude fr...
متن کاملMeteosat Second Generation: On-Ground Calibration, Characterisation and Sensitivity Analysis of SEVIRI Imaging Radiometer
The Meteosat Second Generation (MSG) programme consists of a series of 3 geostationary satellites, the objectives of which were defined by the European meteorological community led by the European Space Agency (ESA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT). The development and procurement of MSG is under the responsibility of ESA. Alcatel France...
