SEVIRI Physical Retrieval
WMO Satellite Skills
The Physical Retrieval algorithm of NWC SAF retrieves the atmospheric temperature and moisture profiles as well as surface skin temperature.
The SEVIRI Physical Retrieval (SPhR) algorithm retrieves the atmospheric temperature and moisture profiles as well as surface skin temperature for one clear sky SEVIRI pixel, or a Field-Of-Regard (FOR) with contains M x M pixels. The central aim of the SPhR is to provide information on the water vapor contained in a vertical column of unit cross-section area in several layers in the troposphere and to provide some instability indices. These parameters are calculated from the retrieved profiles of temperature and humidity.
