==== Satellites  (GOP-7) ==== 

**SEVIRI** on [[http://www.eumetsat.int/Home/Main/What_We_Do/Satellites/Meteosat_Second_Generation/index.htm?l=en|Meteosat Second Generation]] (**MSG**), **MODIS** and **MERIS** observations are  by a near real time (NRT) processing. The information is [[http://wew.met.fu-berlin.de/nrt|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 [[:quicklooks:gop7_msg_cmas:tci|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|meteorological stations]] within the LMK domain, e.g. Cabauw, Lindenberg, COPS supersites.
  * **Areal statistics** will be produced for [[:model_evaluation#areas_for_the_evaluation|selected regions]] and compared to LMK output on a regular, operational basis.
