How warm the Atlantic sea surface is (Meteosat MSG-3)

GHRSST Level 2P Atlantic Regional Skin Sea Surface Temperature from the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) on the Meteosat Second Generation (MSG-3) satellite (GDS version 2)
ocean NASA POCLOUD Level 2P netCDF-4
In plain English

What it measures. The temperature of the skin of the sea surface over the Atlantic region, updated every 15 minutes at about 5 km resolution, with error statistics.

How it's made. Calculated from the infrared channels of the SEVIRI instrument on the geostationary Meteosat-9 (MSG-3) satellite, processed by NOAA.

How & where you'd use it. The frequent updates make it useful for tracking fast-changing ocean conditions, weather, and short-term temperature events over the Atlantic.

Official description

The Meteosat Second Generation (MSG-3) satellites are spin stabilized geostationary satellites operated by the European Organization for the Exploitation of Meteorological Satellites (EUMETSAT) to provide accurate weather monitoring data through its primary instrument the Spinning Enhanced Visible and InfraRed Imager (SEVIRI), which has the capacity to observe the Earth in 12 spectral channels. Eight of these channels are in the thermal infrared, providing among other information, observations of the temperatures of clouds, land and sea surfaces at approximately 5 km resolution with a 15 minute duty cycle. This Group for High Resolution Sea Surface Temperature (GHRSST) dataset produced by the US National Oceanic and Atmospheric Administration (NOAA) National Environmental Satellite, Data, and Information Service (NESDIS) is derived from the SEVIRI instrument on the second MSG satellite (also known as Meteosat-9) that was launched on 22 December 2005. Skin sea surface temperature (SST) data are calculated from the infrared channels of SEVIRI at full resolution every 15 minutes. L2P data products with Single Sensor Error Statistics (SSES) are then derived following the GHRSST-PP Data Processing Specification (GDS) version 2.0.
