Short NameAVHRR_SST_METOP_B-OSISAF-L2P-v1.0
DescriptionA 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 Advanced Very High Resolution Radiometer (AVHRR) on the European Meteorological Operational-B (MetOp-B) satellite (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. Global AVHRR level 1b data are acquired at Meteo-France/Centre de Meteorologie Spatiale (CMS) through the EUMETSAT/EUMETCAST system. SST is retrieved from the AVHRR infrared channels (3.7, 10.8 and 12.0 micrometer) using a multispectral algorithm. Atmospheric profiles of water vapor and temperature from a numerical weather prediction model, together with a radiatiave transfer model, are used to correct the multispectral algorithm for regional and seasonal biases due to changing atmospheric conditions. This product is delivered at full resolution in satellite projection as metagranule corresponding to 3 minutes of acquisition. The product format is compliant with the GHRSST Data Specification (GDS) version 2.

SENSOR
Name: Advanced Very High Resolution Radiometer (AVHRR)
Swath Width: 2400 km
Description: Advanced Very High Resolution Radiometer. This radiometer has the capability to provide detailed maps of thermal radiation from the sea surface, and clouds. The AVHRR operates in two modes: 1) High Resolution Picture Image or HRPT mode, which are high density images with 1km resolution, and are transmitted directly to local ground stations and 2) Global Area Coverage, or GAC mode, which are the same observations as are transmitted during the HRPT mode, but averaged together to obtain a value representative of an area 4km in diameter. GAC data are digitized and recorded on the satellite to provide global coverage.
