During the government shutdown, our branch server,
polar.ncep.noaa.gov, suffered a severe hardware failure and was taken
off-line for repairs. We now have new hardware in place, but products
are not yet up to date. Additionally, a number of archival products,
such as the wave model hindcast archive, sea ice monthly analysis
archive, Global RTOFS graphics archives, and others, are missing or
have gaps. We are working in getting all current products up to date,
and backfilling the archive gaps as much as possible.
The operational ocean wave predictions of NOAA/NWS/NCEP use
the wave model WAVEWATCH III®
using operational NCEP products as input
code is available).
The model is
run four times a day: 00Z, 06Z, 12Z, and 18Z. Each run starts
with 9-, 6- and 3-hour hindcasts and produces forecasts of every 3 hours from the
initial time out to 180 hours (84 hours for the Great Lakes).
The wave model suite consists of global and regional nested grids.
As background information, a list of selected references
and a chronological list of model changes are
available. Finally, validation data are available for the multi-scale model.

NOAA WAVEWATCH III® CFSRR Reanalysis Hindcasts
To generate a wave climatology, a simulation of the 30-year period of
1979-2009 has been run with the NOAA WAVEWATCH III®
using the Tolman-Chalikov physics package with 16
regular lat-lon grids and the new
NCEP Climate Forecast System Reanalysis
and Reforecast (CFSRR) homogeneous data set of hourly 1/2° spatial resolution
