Physical Retrieval

Published: 21 June 2011

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.
