O Products / Sea surface temperature
Arctic Sea surface temperature product products (on the left SST and on the right min SST) based upon observations from the Metop_A AVHRR instrument. The product is products are a daily interpolated field with a 0.05 degrees resolution, and covers surface temperatures in the ocean, the sea ice and the marginal ice zone.

Product Description
Several satellite instruments are used to measure sea surface temperature (SST) with high accuracy based on the principles of infrared radiation, which is emitted by the Earth's surface, including the ocean. Table 1 shows some satellite instruments for measuring SST.

BUSINESS PROCESS | SCE |
DESCRIPTION | Sea surface temperature (SST) is a measurement of the ocean’s temperature close to the surface |
EO INFORMATION OF INTEREST | Sea surface temperature (SST) details the sea temperature between the depths of from approximately 10 µm below the surface (infrared bands) to 1mm (microwave bands) depths using radiometers. |
MAIN PROCESS STEPS | Data is gathered from different satellites, Metop-A, VIIRS_NPP, NOAA 20 and Sentinel A and B. SST data is corrected for bias and then processed through optimal interpolation creating temperature maps. Temperatures data is validated using both drifting and moored in situ buoys. Data which contains clouds or more than 70% ice is discarded. |
INPUT DATA SOURCE | Infrared data from AVHRR on Metop-A, VIIRS_NPP, and NOAA 20. SLSTR data from Sentinel 3 A and B |
SPATIAL RESOLUTION AND COVERAGE | Arctic: 6km from 1982-ongoing Baltic: 2km from 1982-ongoing 4-9km day and night capability VIIRS and MODIS from 2002 - ongoing |
ACCURACY / CONSTRAINS | The cloud cover makes measurement and consequently the generation of the product impossible |
LIMITATIONS | Cloud cover. The interpretation of data can indeed be challenging, especially when handled by personnel without extensive experience in the field. |
TEMPORAL RESOLUTION/ | Various products with various frequency, including hourly, daily mean and monthly |
UPDATE FREQUENCY | Various products with various frequency, including daily-monthly-yearly- twice yearly |
DELIVERY / OUTPUT FORMAT | NetCDF-3 |
ACCESSIBILITY | Copernicus marine service, NASA LAADS DAAC |
