WOCE-SAC Numerical Model Analyses
Various global products of surface fluxes are available to the community. We
have attempted to compile information on relevant air-sea flux datasets of
interest to the WOCE community.
We have made arrangements to distribute the US Navy surface wind/stress
products. Additionally, we have compiled information on reanalysis products.
The NCEP reanalyses are freely available, while the ECMWF reanalyses (ERA) are
available for purchase (US and elsewhere) or through arrangements with member
state distribution facilities (European countries).

A mailing list exists to distribute bulletins from NCAR/DSS and ECMWF about
ECMWF datasets at NCAR such as announcements of data updates, problems which
have been discovered, and changes to software. This mailing list covers the
ECMWF/TOGA (WCRP) archive as well as the reanalyses.
Previous bulletins
are available. If you wish to be added to this mailing list, send email to
Ilana Stern
(ilana@ncar.ucar.edu).
