Sea surface temperature (SST) is the water temperature close to the ocean's surface. The exact meaning of surface varies according to the measurement method used, but it is between 1 millimeter (0.04 in) and 20 meters (70 ft) below the sea surface.
Unit: Celsius
Resolution: 0.25° pixel, daily, monthly
Duration: Jan. 1997 to Dec. 2016.
Source: AVHRR, Optimum Interpolation Sea Surface Temperature (OISST), NOAA's National Centers for Environmental Information
Version: 2.0
Processing: All the daily data in a month are averaged to get the monthly data.
The NOAA 1/4° daily Optimum Interpolation Sea Surface Temperature (or daily OISST) is an analysis constructed by combining observations from different platforms (satellites, ships, buoys) on a regular global grid. A spatially complete SST map is produced by interpolating to fill in gaps. The satellite SSTs we used in this dataset is from AVHRR.
Known issues
The three inputs to the daily OISST require different preparation, as described in Reynolds et al. (2007). The in-situ SSTs need to be checked for outliers, and then averaged onto the 1/4° grid, separately for ships and buoys. The ship data are adjusted to the buoys by subtracting a constant 0.14°C. Similarly, satellite temperatures are averaged onto the analysis grid, after which they are bias-adjusted to the in-situ data. For the marginal ice zone, where there is little in situ data, proxy SSTs are generated from sea ice concentrations. The interpolation step combines the prepared inputs. Banzon et al. (2016) provides more details on the input datasets used.
