The Metop-SG A and Metop-SG B satellites
Metop-SG A and Metop-SG B are the two types of multi-instrument satellites that make up the EUMETSAT EPS-SG. They operate in the same orbit with different configurations. The benefits or applications of this mission are focused on weather forecasting, climate change, air quality (atmospheric composition), hydrology, oceanography, etc. Metop-SG A is also the satellite with the 3MI instrument.
The METImage mission
MetImage (VII) is one of the instruments on Metop-SG A. It is a visible and infrared imager developed by DLR. It provides information on clouds, cloud cover, surface characteristics, ground temperature, ice and surface water. This is made possible by:
-
-
- a large number of spectral channels to measure more variables
- higher spatial sampling (500 m): more complete coverage
- better radiometric resolution for more accurate quantification
-
The EUMETSAT HQ MCC (Mission Control Centre) is composed, among others, of the PDAP (Payload Data Acquisition and Processing) in charge of the acquisition and processing of instrument data, in particular from VII.

The unit is in charge of implementing the PGFs (Processing Generation Functions) of instrument VII in the PDAP processing chains. This processing allows the generation of L1B and L2CM level products:
-
-
- L1B (level 1B): calibrated and navigated radiances in 20 spectral channels at 500 m sampling
- L2CM (level 2 cloud mask)
-
More details on the MetImage mission can be found on the EUMETSAT website.
