The West Coast ROMS configuration is run by the UC Santa Cruz Ocean Modeling group and covers the whole West Coast at a resolution of 10 km. The portal displays the ‘best of’ time series aggregation based on assimilations of the prior 4 days of data (hindcast and nowcast data are also available from UCSC). Parameters displayed in the portal include sea surface height, water temperature, salinity, currents and surface heat flux (other ocean parameters are available in the raw data files). Several physical data sets are assimilated to estimate these parameters. VISO Sea Level Anomalies and subtidally averaged tide-guage data provide information of the sea surface height. OSTIA Sea Surface Temperature and AQUARIUS Sea Surface Salinity provide additional sea surface information. Subsurface hydrography derives from several platforms: Argo buoys provide subsurface information broadly throughout our domain. In addition, glider lines in the central and southern California regions are supported by SCCOOS and CeNCOOS. Glider information off the Washington coast is supported by NANOOS.
IOOS Modeling Community of Practice Models and Products
The IOOS® Regional Associations, academic, industry, and local and state government partners use models and tailored model products to understand and communicate current marine conditions, and forecast future marine conditions. Multiple user focused applications and products are often developed from one model, making the IOOS® Modeling Community of Practice model portfolio efficient and specifically tailored to stakeholder needs in their respective regions. IOOS® delivers and disseminates these models, forecasts, and products so that decision-makers can take action to improve safety, enhance the economy, and protect the environment.
Often, models developed by IOOS® partners are transitioned to NOAA for operational use; these are not included in the IOOS® modeling catalog, but are included in NOAA’s Operational Forecast Systems and Harmful Algal Bloom (HAB) forecasts. Additional model outputs from IOOS® partners can also be visualized in the IOOS® Model Viewer.
WHY USE MODELS?
IOOS uses models to understand current marine conditions, and forecast and predict future marine conditions.
Data Models organize and standardize data elements to understand how they relate to one another and to ocean, coastal, and Great Lakes properties
Model Applications translate and visualize modeling outputs to make data easier to see and understand.

STPS uses IOOS’ High Frequency Radar network to create detailed surface current predictions 24 hours into the future on the East Coast, West Coast, Gulf of America, Florida, Hawaii, and Puerto Rico regions.
The ECCOFS domain spans the eastern seaboard of North America and Intra-Americas Seas from the Grand Banks of Newfoundland in the north to the mouth of the Orinoco River, Venezuela, in the south. ECCOFS will complement the existing WCOFS (West Coast Operational Forecast System) to achieve complete forecast coverage of U.S. territorial seas adjacent to the 48 contiguous states and Puerto Rico. Each day ECCOFS generates an ocean analysis using the Regional Ocean Modeling System (ROMS) 4-Dimensional Variational (4D-Var) data assimilation (DA) system constrained by ocean observations. The forecast resolution is 3 km in the horizontal at 50 vertical terrain-following levels.
The Pathogen Forecast Model hosted by the Southern California Coastal Ocean Observing System (SCCOOS) at Scripps shows the forecasted levels of sewage in the coastal ocean in the San Diego-Tijuana border region together with illness risk for ocean swimming. The Pathogen Forecast Model website provides detailed forecasts for Playas Tijuana, Imperial Beach, Silver Strand State Park, and Coronado of shoreline sewage concentrations as well as estimated risk of illness for ocean swimmers.
The Simulating WAves Nearshore (SWAN) model is a 14-day, hourly forecast for the region surrounding the Republic of Palau at approximately 275-m resolution. The forecast is run daily and is updated on the website around 8:15 AM Palau Time (UTC+9) every morning. This high-resolution wave model helps capture shallow water effects and nearshore coastal dynamics such as refracting, shoaling, and shadowing to provide a general indication of the nearshore environment.

The East Florida Coastal Ocean Model (EFCOM) is an application of unstructured grid model FVCOM in the coastal region of East Florida, from Jekyll Island, GA in the North to Florida Key in the South. It downscales from the deep ocean, across the continental shelf and into esturies by nesting within the Global HYCOM with added tides. It is set to be an automated coastal ocean circulation nowcast/forecast system that updates each day providing 1-day hindcast and a 3.5-day forecast.
The West Florida Coastal Ocean Model (WFCOM) is an application of unstructured grid model FVCOM in the coastal region of the eastern Gulf of America. It downscales from the deep ocean, across the continental shelf and into the estuaries by nesting within the Global HYCOM with added tides, aiming at realistic simulation of the ocean circulation.
Tampa Bay Coastal Ocean Model (TBCOM) is an application of the unstructured grid Finite Volume Community Ocean Model (FVCOM) to the Tampa Bay region, including Tampa Bay, Sarasota Bay, the Intra-Coastal Water Way, and all of the inlets connecting these water bodies with the adjacent Gulf of America. TBCOM is nested within a larger domain West Florida Coastal Ocean Model (WFCOM) so that is downscales from the deeper Gulf of America, across the West Florida Continental Shelf and into Tampa Bay.
