The 1991-2020 Sea Surface Temperature Normals (NCEI Accession 0282469)

The 1991-2020 climate normals for sea surface temperature (SST) were computed from the NOAA Daily Optimum Interpolation SST (OISST) dataset, in accordance to the climate normals guidelines of the World Meteorological Organization (WMO). The product includes SST mean, standard deviation, count, and extreme parameters. The spatial coverage of the product is on 0.25° spatial grids. This normals dataset is generated based on the 1991-2020 daily OISST with outputs of mean parameters for daily, monthly, seasonal, and annual time scales. The 15-year normals for the period 2006-2020 are also computed as a supplemental product. The data files are in netCDF format.
