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.
