U.S. Navy FNOC Northern Hemisphere Sea Surface Temperature Analyses, daily November 1961 to December 1993

Earlier grids DSS received "stand alone," later grids were extracted by DSS from the "full stack" of grids in DS240.1 [rda.ucar.edu/datasets/ds240.1/] Unless you have a special interest in this dataset, DSS recommends that you use one of our reanalysis datasets, such as ds090.0 [rda.ucar.edu/datasets/ds090.0/]. That's because those are based on a more complete collection of observations, improved analysis methods, and are provided in a common modern format (GRIB).
