METIS-AOD, the Copernicus S3 NRT Aerosol Optical Depth component of Monitoring & Evaluation of Thematic Information from Space (METIS), provides near-real time diagnostics of EUMETSAT preliminary operational level-2 (L2) satellite AOD products.

Current Satellite NRT Sentinel-3 AOD Products monitored in METIS-AOD NRT S3 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 18 Regions of interest (ROI).

A series of additional NRT S3 AOD dataset produced off-line from the same EUMETSAT processor can be made available upon request. This includes complete worldwide reprocessing of past NRT S3 AOD dataset from several months of 2019 and 2020 based on the reference NRT configuration, Baseline Collection 1 Processor v2.0. More details available on the EUMETSAT NRT Sentinel-3 Atmospheric Composition Webpage.
