Monitoring & Evaluation of Thematic Information from Space

Partners & collaborators

METIS-SST, the Sea Surface Temperature component of Monitoring & Evaluation of Thematic Information from Space (METIS), provides near-real time diagnostics of EUMETSAT operational level-2 (L2) satellite SSTs.

Current Satellite SST Products monitored in METIS-SST are from: Sentinel-3A SLSTR, Metop-B (M1) AVHRR and M1 IASI.

The satellite SSTs are monitored employing uniformly gridded Level-4 daily Canadian Meteorological Centre (CMC), daily UKMO OSTIA and monthly climatological OSTIA data as Reference fields. Validation against in situ SSTs will be performed as the Sentinel-3A products mature.

All analyses are performed Globally & for 15 selected Regions of interest (ROIs).
