The Central Facility is based at the EUMETSAT headquarters in Germany.
The Product Navigator has a full list of products, which primarily support the application needs for Nowcasting and Numerical Weather Prediction (NWP).
Level 1 satellite data
Raw sensor data are received from the ground stations and forwarded to dedicated processing facilities within the Central Facility. These facilities generate the level 1 data and products.
In the case of Meteosat image processing, line-by-line processing ensures that imperfections are removed during the generation of the level 1.5 satellite data. In particular, the data from the various on-board sensors are realigned by resampling, in order to make the image from each set of detectors coincide with the other images.
At the same time, the sampling removes the slight perturbations caused by the movement of the spacecraft, rectifying the image so it appears to come from the nominal location of the spacecraft (geometric correction). Adjustments to the individual data values are made according to calibration information. Once each line of the level 1.5 products is complete it is passed to the dissemination computers for immediate relay to users and to higher processing facilities within the Central Facility and the SAFs.
Level 2 processed products
In the case of Meteosat processing, the facility receives near-real-time level 1.5 data from the image processing system, which has performed a geometrical correction and removed imperfections in the images. A radiative transfer model is applied to compute expected radiances at the top of the atmosphere, as well as atmospheric correction tables.
Scenes analysis provides information on the surface type in each cloud-free image pixel. This output is then presented to the various meteorological product applications as a classified pixel map and segmented clustered scenes. Meteorological products are then generated.
In addition to the EUMETSAT satellite data, input from sources external to EUMETSAT is required for the processing and verification of some products. Independent meteorological observations are used to verify a subset of the products, and verification results are stored with the products.
Products generated within the Central Facility are subject to a validation processes to ensure the correct quality of product has been reached. All products need to meet validation criteria before an 'operational' product validation status can be applied. Corresponding validation reports are made available at the time of the product release.
Archiving data and products
All data and products generated within the Central Facility are archived in the EUMETSAT Data Centre and can be retrieved, on demand, by users.
The EUMETSAT Mission Control Centres (MCC) are responsible for the safe operations of all our satellites.
Satellite Application Facilities (SAFs)
Utilising specialist expertise from the Member States, Satellite Application Facilities (SAFs) are dedicated centres of excellence for processing satellite data.
Metop ground segment
The EUMETSAT Polar System (EPS) ground station is located on Spitsbergen, Svalbard.
MTG ground segment
The ground segment will acquire data from MTG satellites, generate, archive and distribute data.
EPS-SG ground segment
The EPS-SG Overall Ground Segment (OGS) will support the ground functions required to meet the EPS-SG Missions objectives.
How to access our data
We offer a portfolio of data access options that allow users to view imagery and access and download data.
Scientific studies for the evolution of operational products suite and for the development of new products.
Meteosat satellites have been providing crucial data for weather forecasting since 1977.
