Sea surface temperature over the North Atlantic (MetOp)

GHRSST Level 3C North Atlantic Regional (NAR) subskin Sea Surface Temperature from Metop/AVHRR (GDS V2) produced by OSI SAF
ocean NASA POCLOUD Level 3 netCDF-4
In plain English

What it measures. Sea surface temperature (how warm the ocean is just under the surface) focused on the North Atlantic region, on a fine 2-kilometer grid.

How it's made. Retrieved from infrared channels of the AVHRR instrument on Europe's MetOp-B satellite using a multi-channel method, delivered as four files covering six-hour periods each day.

How & where you'd use it. Supports near-real-time ocean and weather monitoring over the North Atlantic and feeds into larger sea-temperature analyses.

Official description

A Group for High Resolution Sea Surface Temperature (GHRSST) dataset for the North Atlantic Region (NAR) derived from the Advanced Very High Resolution Radiometer (AVHRR) on the European Meteorological Operational-B (MetOp-B) platform (launched 17 Sep 2012). The European Organization for the Exploitation of Meteorological Satellites (EUMETSAT), Ocean and Sea Ice Satellite Application Facility (OSI SAF) is producing SST products in near real time from Metop/AVHRR and SNPP/VIIRS. Global AVHRR level 1b data are acquired at Meteo- France/Centre de Meteorologie Spatiale (CMS) through the EUMETSAT/EUMETCAST system. NAR SNPP/VIIRS level 0 data are acquired through direct readout and converted into l1b at CMS. SST is retrieved from the AVHRR and VIIRS infrared channels using a multispectral algorithm. This product is delivered as four six hourly collated files per day on a regular 2km grid. The product format is compliant with the GHRSST Data Specification (GDS) version 2.
