Fleet Numerical Oceanographic Center in Monterey California prepares many analyses, from which we receive this surface subset on a 63x63 grid. It includes sea surface temperature, air surface temperature, surface vapor pressure, 19.5m surface winds, and sea level pressure.

Unless you have a special interest in this dataset, DSS recommends that you use one of our reanalysis datasets, such as 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).
