SUPPLEMENTARY DOCUMENTATION
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).
Please see the
supplemental information
for ds082.0, the source of this dataset. Also the ds082.0
documents
VARIABLES:
About 1991, NCEP acknowledged that the temperature is
actually virtual temperature. I.e., Q=16 means virtual temperature.
A humidity field problem is described
here.
Some wind field problems are described
here.
Sea surface temperatures, based on Navy analyses, begin 1979May16. For earlier
analyses, see DS240.0.
Snow depth analyses begin 1979Jul25 and appear just once a week or so.
Surface elevation field from DS757.0.
