Satellites (GOP-7)

SEVIRI on Meteosat Second Generation (MSG), MODIS and MERIS observations are by a near real time (NRT) processing. The information is online with a delay of 2 hours. The SEVIRI instrument on MSG with its 11 spectral channels from 0.6 to 14 μm will be the prime instrument.

True color images (TCI) composed from 1.6, 0.8 and 0.6 μm radiances are available as daily movies
Products are generated from the calibrated satellite data automatically to provide higher-order, level 2 products, e.g. cloud mask (CM), cloud optical thickness (τ), cloud top pressure (CTP) and integrated water vapor (IWV).
Time series (stst) is extracted from SEVIRI products to monitor atmospheric products at meteorological stations within the LMK domain, e.g. Cabauw, Lindenberg, COPS supersites.
Areal statistics will be produced for selected regions and compared to LMK output on a regular, operational basis.
