Subject: Corrected: NOS/CO-OPS is implementing model guidance
Standard Hydrometeorological Exchange Format (SHEF)
Bulletins, Effective December 5, 2012.
Corrected to indicate 12 OFS models will be released in SHEF
Bulletins, not 13, and to include AWIPS Identifiers (AI) and WMO
Headers for each SHEF Bulletin and the SHEF type-source code.
Effective December 5, 2012 at 1500 Coordinated Universal Time
(UTC), NOS/CO-OPS will implement SHEF Bulletins using type-source
code HMIFU for CO-OPS Operational Forecast System (OFS) water
level model guidance.
CO-OPS currently produces SHEF bulletins of observed water level
and meteorological data as well as astronomical tides. A new set
of SHEF bulletins will be generated with total water level model
guidance from the 12 operational CO-OPS OFS models. Ten OFS
models (Chesapeake Bay, Delaware Bay, Tampa Bay, Northern Gulf of
Mexico, Columbia River Estuary, and the five Great Lakes models)
produce 48-hour model guidance of time series data updated every
6 hours, and two models (New York/New Jersey and St. Johns River)
provide 24-hour model guidance updated every 6 hours.
Model guidance is provided at the CO-OPS tide gauge locations.
Thus, the OFS Water Level SHEF bulletins will contain the full
48-hour or 24-hour model guidance of 30-minute data and will be
issued every 6 hours to remain consistent with the OFS output.
Modeled water levels are total water levels (astronomical tide
plus surge). It is noted that CO-OPS models are not designed as a
storm surge model, though meteorological parameters such as winds
and air pressure are taken into account. Although the Operational
Forecast Systems produce model guidance of currents, water
temperature, and salinity, these data will not be included in the
SHEF bulletins; however, they can be viewed and downloaded at the
CO-OPS web site. The Great Lakes SHEF OFS data will be in Local
Standard Time (LST), whereas the rest of the OFS data will be in
UTC, to meet user requirements.
The WMO header and AWIPS Identifiers (AI) for each OFS SHEF
Bulletin (bulletins are grouped by OFS):
