Monitoring of precipitation with Meteosat

Advances in Space Research, 1989
Abstract Rainfall has been estimated at the European Space Operations Centre (ESOC) since 1985 using the ESOC Precipitation Index (EPI), a statistical cloud indexing method which assumes that the larger the cold cloud core, the heavier the precipitation.

The Meteosat system during the FGGE

Advances in Space Research, 1981
Abstract The Meteosat system is described, together with a description of its performance during the operational year of the FGGE. The paper starts with an overall description, including both the spacecraft and ground system. A review is made of its performance in respect of image taking, dissemination of data, data collection from environmental ...

Infrared Sounder For Second Generation Meteosat

SPIE Proceedings, 1988
This paper provides the main outcomes from studies dedicated to the Infrared Sounder for Second Generation Meteosat. These studies are performed by Matra Space Branch and supported by European Space Agency (ESA) and Centre National d'Etudes Spatiales (CNES).

An image geometry model for METEOSAT†

International Journal of Remote Sensing, 1985
Abstract METEOSAT is a spin-stabilized geostationary satellite which takes Earth images in three spectral channels, infrared, visible and water vapour absorption band. The time-dependent deviations of the satellite from nominal position, attitude and spin speed are described by an image geometry model.

The Meteosat-P2 radiation effects experiment

Acta Astronautica, 1990
Abstract The Radiation Effects or “Latch-Up Experiment” flown on Meteosat-P2 is an excellent example of the technology demonstration concept. It was implemented as an experiment-of-opportunity in a 10-month timescale following the late withdrawal of another experiment.

M.I.S. — the meteosat image simulator

Mathematics and Computers in Simulation, 1977
Abstract A simulator has been implemented which produces simulated telemetry data for the high speed image (radiometer) channel and the attitude part of the housekeeping channel. In this paper we shall describe parts of this simulator ∗∗∗ which are interesting from the point of view of image processing and computer graphics.

Evidence for differential charging on meteosat-2

Journal of Electrostatics, 1987
Abstract Operational problems with Meteosat-1 led to a collaborative effort to furnish subsequent spacecraft with simple charging monitors and to study the geosynchronous environment in an attempt to better understand the charging process. The electron spectrometer on Meteosat-2 has yielded a continuous data set since 1982 which has clarified the ...

Geometric cloud heights from Meteosat

International Journal of Remote Sensing, 2004
Atmospheric Motion Vectors (AMVs) constitute an integral part of the global observing system. The heights of these vectors are determined by the target temperature, which, in the case of semi-transparent or broken clouds, is corrected for the upwelling radiance from scenes below the target.

On the calibration of the Meteosat water vapor channel

Journal of Geophysical Research: Atmospheres, 1995
The calibration of the Meteosat water vapor channel image data is of prime importance for a quantitative use. The vicarious calibration technique employs the use of data from radiosonde ascents. A screening technique, removing spurious radiosonde information, has been improved and used operationally since February 4, 1994.

Calibration of the VIS-channel of meteosat-2

Advances in Space Research, 1983
The “VIS-channel” (the channel is sensitive between about .4 and 1.1 μm wavelength) of the European geostationary satellite Meteosat-2 is calibrated by the method of “vicarious calibration by means of calculated radiances”. The calibration constant, which connects the 6-bit-counts of the VIS-channel of the Meteosat-2 with the corresponding “effective ...
