| Short Name | DMI-L4UHfnd-NSEABALTIC-DMI_OI |
| Description | A Group for High Resolution Sea Surface Temperature (GHRSST) Level 4 sea surface temperature analysis produced daily on an operational basis by the Danish Meteorological Institute (DMI) using an optimal interpolation (OI) approach on a regional 0.03 degree grid. The analysis is based upon nighttime GHRSST L2P skin and subskin SST observations from several satellites over the North and Baltic Seas. The sensors include the Advanced Very High Resolution Radiometer (AVHRR), the Advanced Along Track Scanning Radiometer (AATSR), the Spinning Enhanced Visible and Infrared Imager (SEVIRI), the Advanced Microwave Scanning Radiometer-EOS (AMSRE) and the Moderate Resolution Imaging Spectroradiometer (MODIS) on Aqua. An ice field from the Swedish and Finnish ice services is used to mask out areas with ice. |

| Platform/Sensor | AQUA / Platform Name: Earth Observing System, AQUA (AQUA) Orbit Period: 98.8 minutes Inclination Angle: 98 degrees Ascending Node: - AMSR-E SENSOR Name: Advanced Microwave Scanning Radiometer-EOS (AMSR-E) Swath Width: 1445 km Description: The Advanced Microwave Scanning Radiometer for EOS (AMSR-E) is a twelve-channel, six-frequency, total power passive-microwave radiometer system. AQUA / Platform Name: Earth Observing System, AQUA (AQUA) Orbit Period: 98.8 minutes Inclination Angle: 98 degrees Ascending Node: - MODIS SENSOR Name: Moderate-Resolution Imaging Spectroradiometer (MODIS) Swath Width: 2330 km Description: The MODIS (Moderate Resolution Imaging Spectroradiometer) instrument provides high radiometric sensitivity (12 bit) in 36 spectral bands ranging in wavelength from 0.4 m to 14.4 m. It is used for observing processes occurring on the land, in the oceans, and in the lower atmosphere. ENVISAT / Platform Name: Environmental Satellite (ENVISAT) Orbit Period: 100.59 minutes Inclination Angle: 98.55 degrees Ascending Node: - AATSR SENSOR Name: Advanced Along-Track Scanning Radiometer (AATSR) Swath Width: 500 km Description: Advanced Along-Track Scanning Radiometer (AATSR) is one of the Announcement of Opportunity (AO) instruments on board the European Space Agency (ESA) satellite ENVISAT. It is the most recent in a series of instruments designed primarily to measure Sea Surface Temperature (SST), following on from ATSR-1 and ATSR-2 on board ERS-1 and ERS-2. MSG / Platform Name: Meteosat Second Generation (MSG) Orbit Period: -999 minutes Inclination Angle: -999 degrees Ascending Node: - SEVIRI SENSOR Name: Spinning Enhanced Visible and Infrared Imager (SEVIRI) Swath Width: -999 km Description: The Spinning Enhanced Visible and InfraRed Imager (SEVIRI) 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. NOAA-17 / Platform Name: National Oceanic & Atmospheric Administration-17 (NOAA-17) Orbit Period: 101.2 minutes Inclination Angle: 98.7 degrees Ascending Node: - 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-18 / Platform Name: National Oceanic & Atmospheric Administration-18 (NOAA-18) Orbit Period: 102.12 minutes Inclination Angle: 98.74 degrees Ascending Node: - 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. |
