How warm the Atlantic sea surface is (Meteosat SEVIRI, per-pass)

NOAA GHRSST Level 2P Atlantic Ocean Regional Skin Sea Surface Temperature v1.0 from the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) on the Meteosat Second Generation-4 (MSG-4) satellite
ocean NASA POCLOUD Level 2P netCDF-4
In plain English

What it measures. How warm the skin of the Atlantic Ocean surface is, captured frequently throughout the day at about 3-kilometer detail. Each file covers one full-disk view of the region.

How it's made. Produced by NOAA from the SEVIRI imager aboard Europe's Meteosat (MSG) satellites, which sit fixed over the Atlantic and scan every 15 minutes.

How & where you'd use it. Feeds weather forecasting, atmospheric and climate studies, and ocean monitoring. It also includes uncertainty estimates for each measurement.

Official description

The GHRSST L2P MSG04 SST v1.0 dataset is produced by the US National Oceanic and Atmospheric Administration (NOAA) National Environmental Satellite, Data, and Information Service (NESDIS) from the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) onboard the Meteosat-11 (MSG4) satellite. It provides the full disk SEVIRI imagery covering the Atlantic Ocean region from its position at 0.0°E longitude. The L2P SST is produced at approximately 3 km resolution with a 15 minute duty cycle. On Feb. 2, 2018 the Meteosat-11 (MSG4) took over the Meteosat-10 (MSG3) (MSG03-OSPO-L2P-v1.0) and produced the L2P SST data from Sept 10. 2018 to March 24, 2023. In March 2023, Meteosat-10 and Meteosat-11 were swapped roles and orbital positions. The MSG03 has started to produce the L2P SST data again over the Atlantic Ocean region. Be aware that the granules before Dec. 1, 2022 contain some uncorrected metadata errors. The SST measurements from SEVIRI are parameters in study of the weather, atmosphere, climate and ocean environments. Meteosat satellites have been providing crucial data for weather forecasting since 1977. This L2P SST product which includes Single Sensor Error Statistics (i.e., uncertainty statistics) follows the GHRSST Data Processing Specification (GDS) version 2.0 format guidelines. Please refer to the user guide for more information.
