Short Name	IASI_SST_METOP_A-OSISAF-L2P-v1.0
Description	A global 1 km Group for High Resolution Sea Surface Temperature (GHRSST) Level 2P dataset based on multi-channel sea surface temperature (SST) retrievals generated in real-time from the Infrared Atmospheric Sounding Interferometer (IASI) on the European Meteorological Operational-A (MetOp-A）satellite （launched 19 Oct 2006). 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/IASI. The Infrared Atmospheric Sounding Interferometer (IASI) measures in the infrared part of the electromagnetic spectrum at a horizontal resolution of 12 km at nadir up to 40km over a swath width of about 2,200 km. With 14 orbits in a sun-synchronous mid-morning orbit (9:30 Local Solar Time equator crossing, descending node) global observations can be provided twice a day. The SST retrieval is performed and provided by the IASI L2 processor at EUMETSAT headquarters. The product format is compliant with the GHRSST Data Specification (GDS) version 2.
