On July 25, 2013, NCEP will transition from the current operational Central Computing System (CCS) to the Weather and Climate Operational Supercomputing System (WCOSS). Live tests have been run with dissemination of data on June 25th and July 2nd. Due to the transition, there will be some product changes. They are listed below:
The CREOFS field output files are being broken into individual files by hour:
nos.creofs.fields.[n|f]FF.YYYYMMDD.tCCz.nc > nos.creofs.fields.[n|f]0FF.YYYYMMDD.tCCz.nc
For example, new file names of hour 00 nowcast and forecast field outputs at the 03z cycle are:
CC is the model cycle runtime (i.e. 00, 06, 12, 18 for CBOFS, DBOFS, and TBOFS, 03,09,15,21 for NGOFS and CREOFS)
YYYY is the calendar year of model runtime
MM is the calendar month of model runtime
DD is the calendar date of model runtime
For questions regarding this change and for questions on how to access NOS OFS products from CO-OPS servers, please the NOCMP Program Manager via email by visiting the CO-OPS Contact Information page.
A Columbia River Estuary Operational Forecast System (CREOFS) has been developed to serve the Oregon and Washington maritime communities. CREOFS was jointly developed by the Oregon Health & Science University (OHSU), the NOAA/National Ocean Service's (NOS) Office of Coast Survey and Center for Operational Oceanographic Products and Services (CO-OPS), and the NOAA/National Weather Service's (NWS) National Centers for Environmental Prediction (NCEP) Central Operations (NCO). The NWS and NOS work together to run CREOFS operationally on NOAA's High Performance Computing System (HPCS). By running on NOAA's HPCS, CREOFS has direct access to National Weather Service operational meteorological products that are required for reliable operations. As its core ocean prediction model, CREOFS uses the Semi-implicit Eulerian-Lagrangian Finite Element (SELFE) model, which was also developed at OHSU.
CREOFS provides users with nowcast (analyses of near present) and forecast guidance of water levels, currents, water temperature, and salinity out to 48 hours, four times per day. The CREOFS model domain is also divided into five separate subdomains (Upper Columbia River , Middle Columbia River, Lower Columbia River, Columbia River Bar Entrance, and the mouth and offshore of the Columbia River), allowing users to focus on their area of interest. Animation maps of each of the five subdomains as well as time series at particular stations or points of interest are available at over 40 locations for winds, water level, currents, temperature, and salinity.
CREOFS is based on a three-dimensional, high resolution model. With the added reliability of running at NOAA's HPCS, CREOFS will assist U.S. port authorities and mariners to efficiently navigate the Columbia River without compromising safety.
