Abstract
Imagery from meteorological satellites can be used to derive sea surface temperature (SST). Geostationary satellites like Meteosat Second Generation (MSG) can also inform us on diurnal variations of SST, a useful information for deriving foundation SST and building multisensor-based analyses. EUMETSAT’s Ocean and Sea Ice Satellite Application Facility (OSISAF) operationally produces SST estimates from MSG’s Spinning Enhanced Visible and Infrared Imager (SEVIRI) observations. We present here ongoing activities for its reprocessing into a climate data record covering the period from 2004 to 2024 for sensors at longitude 0°, on a 0.05° regular grid and with hourly resolution. Hosted by the European Weather Cloud, the reprocessing will notably rely on improved radiance calibration, reprocessed input datasets (cloud mask, climatologies of maximum SST gradients, atmospheric temperature and humidity profiles, a priori SST...) and on consistent radiative transfer simulations from the version 13 of the RTTOV model.
