Monitoring & Evaluation of Thematic Information from Space (METIS)

The Monitoring and Evaluation of Thematic Information from Space (METIS) tool is developed to monitor EUMETSAT operational remotely sensed products for stability, quality and performance on a global and regional basis in routine. The current METIS modules are:

METIS-SST

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-3 SLSTR-A and -B, Metop-B (M1) AVHRR and M1 IASI.
METIS-OC

METIS-OC, the Ocean Colour component of Monitoring & Evaluation of Thematic Information from Space (METIS), provides near-real time diagnostics of EUMETSAT operational level-2 (L2) satellite ocean colour products.

Current Satellite SST Products monitored in METIS-OC are from: Sentinel-3 OLCI-A and -B
METIS-FRP NRT S3

METIS-FRP NRT S3, the FRP component of Monitoring & Evaluation of Thematic Information from Space (METIS), provides near-real time diagnostics of the Copernicus Near Real Time (NRT) Sentinel-3 FRP product procured by EUMETSAT.

Current Satellite FRP NRT Products monitored in METIS-FRP NRT S3 are from: Sentinel-3 SLSTR-A and -B.
METIS-AOD NRT S3

METIS-AOD NRT S3, the AOD component of Monitoring & Evaluation of Thematic Information from Space (METIS), provides near-real time diagnostics of the Copernicus Near Real Time (NRT) Senti nel-3 AOD product procured by EUMETSAT.

Current Satellite AOD NRT Products monitored in METIS-AOD NRT S3 are from: Sentinel-3 SLSTR-A and -B.

The SST component of METIS is inspired by SQUAM, the NOAA SST Quality Monitor, developed by Prasanjit Dash and Alexander Ignatov (NOAA), and is expanded to other thematic information.
