Determination of circumsolar radiation from Meteosat Second Generation

Determination of circumsolar radiation from Meteosat Second Generation

Reliable data on circumsolar radiation, which is caused by scattering of sunlight by cloud or aerosol particles, is becoming more and more important for the resource assessment and design of concentrating solar technologies (CSTs). However, measuring circumsolar radiation is demanding and only very limited data sets are available. As a step to bridge this gap, a method was developed which allow...

Meteosat Second Generation Data for Assessment of Surface Moisture Status

Two approaches for estimation of remotely sensed land surface temperature, Ts, based on MSG-SEVIRI data have been tested in a semi-arid environment in West Africa. A local algorithm, based on in situ measured Ts and a regional algorithm, based on MODIS LST products. They are both based on the split-window technique and show encouraging results, however applications are limited to the region for...

The Image Processing Facility for METEOSAT Second Generation

The first METEOSAT Second Generation satellite will come into service in 2001. It will acquire image data in 12 spectral channels with a total data volume of 265 Mbytes every 15 minutes. These data are received, processed, and distributed by the EUMETSAT Ground Segment in real-time. The Ground Segment architecture is composed of blocks of grouped functionality called facilities. The Image Proce...

Discriminating raining from non-raining clouds at mid-latitudes using Meteosat Second Generation daytime data

A new method for the delineation of precipitation during daytime using multispectral satellite data is proposed. The approach is not only applicable to the detection of mainly convective precipitation by means of the commonly used relation between infrared cloud top temperature and rainfall probability but enables also the detection of stratiform precipitation (e.g. in connection with mid-latit...
