DescriptionA Group for High Resolution Sea Surface Temperature (GHRSST) Level 4 sea surface temperature (SST) analysis produced daily on an operational basis at the Canadian Meteorological Center. This dataset merges infrared satellite SST at varying points in the time series from the Advanced Very High Resolution Radiometer (AVHRR) from NOAA-18,19, the European Meteorological Operational-A (METOP-A) and Operational-B (METOP-B), and microwave data from the Advanced Microwave Scanning Radiometer 2 (AMSR2) onboard the GCOM-W satellite in conjunction with in situ observations of SST from drifting buoys and ships from the ICOADS program. It uses the previous days analysis as the background field for the statistical interpolation used to assimilate the satellite and in situ observations. This dataset adheres to the GHRSST Data Processing Specification (GDS) version 2 format specifications.

InSitu
SENSOR
Name: Ships and Moored and Drifting Buoys (InSitu)
Swath Width: -999 km
Description: In situ SST data from drifting and moored buoys, and ships.

METOP-A
Platform
Name: Meteorological Operational Satellite - A (METOP-A)
Orbit Period: 101.3 minutes
Inclination Angle: 98.7 degrees
Ascending Node: 1970-Jan-01 00:00:00

AVHRR-3
SENSOR
Name: Advanced Very High Resolution Radiometer-3 (AVHRR-3)
Swath Width: 2400 km
Description: The AVHRR is a radiation-detection imager that can be used for remotely determining cloud cover and the surface temperature. Note that the term surface can mean the surface of the Earth, the upper surfaces of clouds, or the surface of a body of water.

NOAA-19
Platform
Name: National Oceanic & Atmospheric Administration-19 (NOAA-19)
Orbit Period: 102.12 minutes
Inclination Angle: 98.74 degrees
Ascending Node: 1970-Jan-01 00:00:00

AVHRR
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.

NOAA-20
Platform
Name: National Oceanic & Atmospheric Administration-20 (NOAA-20)
Orbit Period: 102 minutes
Inclination Angle: 99 degrees
Ascending Node: 1970-Jan-01 00:00:00
