Welcome to the OSSAR-CS3 METIS system - Routinely monitoring the reference Copernicus Sentinel-3 (CS3) L2 NRT Aerosol product procured by EUMETSAT!
METIS is the EUMETSAT Monitoring & Evaluation of Thematic Information from Space (METIS). It provides routine diagnostics of the reference L3 NRT S3 aerosol product directly generated by the operational processor: Optimized Simultaneous Surface Aerosol Retrieval from Copernicus Sentinel-3 (OSSAR-CS3). OSSAR-CS3 is implemented, maintained, incrementaly evolved and lead autonomously by EUMETSAT, directly entrusted by the European Comission (EC) and the Copernicus programme mandates.
Current Satellite L2 NRT Sentinel-3 Aerosol Products are from: Sentinel-3 SLSTR-A and -B.
Further details on this product are described on the EUMETSAT Operational Algorithm Web page - Copernicus Sentinel-3 NRT Aerosol Optical Depth (AOD) Air quality, long-range transport & threat monitoring of suspended air particles
All analyses are stratified into 20 Regions of interest (ROI).
Latest evolution was released on 28th October 2021, and is associated with the OSSAR-CS3 processor v3.0, Processing Baseline 2.0, Collection 2.
The following documents are available with the latest Collection 2: Algorithm theoretocal Basic Document (ATBD) v1.0, Product Validation Report (PVR) v1.A, user Product Notice (PN) v1.A, Product Data Format Specification (PDFS).
OSSAR-CS3 is one of the EUMETSAT operational processors contributing to the Coperncius Sentinel-3 Atmosphere portfolio (including Fires, Clouds, Water Vapour). More details available on the EUMETSAT NRT Sentinel-3 Atmospheric Composition Webpage.
