Columbia River Estuary Operational Forecast System (CREOFS)

Each of the blue icons represent a different CREOFS subdomain. Click on an icon to open the main web page of that subdomain.

A Columbia River Estuary Operational Forecast System (CREOFS) has been developed to serve the Oregon and Washington user 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 subdomain, Middle Columbia River subdomain, Lower Columbia River subdomain, Columbia River Bar Entrance subdomain, and the mouth and offshore subdomain 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.
