SalishSea_ColumbiaR_NOS_W

The Salish Sea and Columbia River Estuary Operational Forecast System (SSCOFS) was developed as a joint project of the NOAA/National Ocean Service's Center for Operational Oceanographic Products and Services (CO-OPS) and Office of Coast Survey, the NOAA/National Weather Service's (NWS) National Centers for Environmental Prediction Central Operations, the Battelle - Pacific Northwest National Laboratory (PNNL), and the University of Massachusetts-Dartmouth. The SSCOFS model domain encompasses the Puget Sound, the San Juan Islands, the Strait of Georgia, and the Strait of Juan de Fuca, and extends south along the Pacific Coast to include the Columbia River. It is divided into 9 separate subdomains (San Juan Islands, Whidbey Basin, Central Puget Sound, Southern Puget Sound, Strait of Juan De Fuca, Columbia River Bar Entrance and Offshore Regions, Lower Columbia River, Middle Columbia River, and Upper Columbia River), allowing users to focus on their area of interest. SSCOFS uses the Finite-Volume, Coastal Ocean Model (FVCOM), and provides nowcast and forecast guidance of water levels, currents, water temperature, and salinity out to 72 hours, 4 times a day. The model relies on the National Water Model output for the river forcing, ADCIRC (ENPAC2015) for the tidal forcing and the Global Real-Time Ocean Forecast System (G-RTOFS) for the subtidal water level, water temperature and salinity profile along open boundaries. The SSCOFS grid has 239,734 nodes and 433,410 elements. The vertical grid follows the terrain and consists of 10 spatially varying sigma-layers. The model has an unstructured triangular grid. The resolution varies from ~ 100 m along the shoreline to 500 m in deeper parts of Puget Sound and the Georgia Basin, and increases to 10,000 m over the continental shelf. Resolution in the Columbia River varies between 100 and 200 m. SSCOFS replaced the CREOFS model.

NDFD2_CONUS

National Digital Forecast Database from the National Weather Service (NWS) is a seamless mosaic of digital forecasts from the NWS field offices working in collaboration with the National Centers for Environmental Prediction (NCEP); https://vlab.noaa.gov/web/mdl/ndfd/" . Gridded wind forecasts are available for CONUS, Puerto Rico, Guam, Hawaii, Alaska, Oceanic and Micronesia. Other NDFD products and regions can be viewed at: https://digital.mdl.nws.noaa.gov . Products relevant to SAR include: Relative Humidity (useful for PSDA); Weather, % cloud cover (Sky cover), and Probability of Precipitation (useful for visibility estimates); and Wave Height (ft).

HRRR_US_W

The HRRR is a NOAA real-time 3-km resolution (1.6 NM), updated hourly, cloud-resolving, convection-allowing atmospheric model, initialized by 3km grids with 3km radar assimilation. Radar data is assimilated in the HRRR every 15 min over a 1-h period adding further detail to that provided by the hourly data assimilation from the 13km radar-enhanced Rapid Refresh. The forecasts run out to 48 hours. Model output parameters are pressure, wind, wind gust, rain, cloud, temperature, humidity, dew point, convection, smoke, simulated radar, precipitable water, lightning, visibility, 0C isotherm, 250 mb, 500 mb, 850 mb.

NAM_CONUS_5km

North American Mesoscale (NAM) models are regional mesoscale data assimilation and forecast model systems. NAM is based on the Weather Research and Forecasting Model (WRF) common modeling infrastructure since June 20, 2007. http://www.dtcenter.org/wrf-nmm/users/OnLineTutorial/NMM/index.php NAM CONUS 12km is currently running at 12 km resolution and 60 layers. NAM forecasts are produced every six hours at 00, 06, 12 and 18 UTC. The NAM graphics are available at six hour increments out to 84 hours. The NAM has non-hydrostatic dynamics and a full suite of physical parameterizations and a land surface model. Information on the model products is found at http://www.nco.ncep.noaa.gov/pmb/products/nam/ page.
