SEVIRI observes the Earth with improved performance compared to its Meteosat predecessors, is particularly beneficial the meteorological "nowcasters" and remote sensing of atmospheric processes. The design incorporates many new features, which provide state-of-the-art pointing accuracy and simultaneous precise multi-spectral radiometry, geared to fulfil the demanding MSG mission objectives.
Data provided by SEVIRI is used in numerical weather forecasting models and in atmospheric and environmental research. Many necessary parameters to understand our environment can be seen: the temperature of the surface and atmosphere, atmospheric water vapour content, cloud formations, storms, hurricanes, heavy rain and fog.
SEVIRI has significantly enhanced technical capabilities:
Technically, SEVIRI is a light-weight and compact telescope and scan assembly plus a complex focal plane. The scan assembly itself consists of an additional movable mirror which is positioned in front of the telescope; it performs a linear scan of the Earth's surface from south to north. The telescope sends the collected radiation to the focal plane where it is divided into twelve different channels of the electromagnetic spectrum and transferred to 42 sensors. The sensors transmit the recorded data to the Functional Control Unit (FCU), the interface to the data transmission system of the MSG satellite. Thus, a new multispectral satellite image is produced every 15 minutes.
Data access to level 1.5 and level 2 MSG data and products via EUMETSAT.
DLR archives full disk SEVIRI HRIT level 1.5 data in its DIMS facility.
The MSG Platform
The Meteosat Second Generation (MSG) has been established in cooperation between EUMETSAT and ESA. Designed in response to requirements addressed by users of EUMETSAT Member States, it serves the needs of Nowcasting applications and Numerical Weather Prediction in addition to providing important data for climate monitoring and research.
