U.S. Navy FNOC Southern Hemisphere Tropospheric Analyses, daily August 1974 to December 1993

Prepared by Fleet Numerical Oceanographic Center in Monterey California. 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).
