SSCOFS provides real-time nowcasts and 2-day forecasts of tides, currents, salinity, and temperature at 6-minute to hourly intervals in the Salish Sea and Columbia River area. Future improvements include resolution enhancements and data assimilation.
IOOS Modeling Community of Practice Models and Products
IOOS® data comes from a variety of instruments that are part of the nationwide observing system, including buoys, high frequency radar systems, water level sensors and gliders. Understanding the current and future state of our Nation’s coasts, oceans, and Great Lakes from these disparate and complex data sets is a challenge.
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.

The WRF numerical forecasts provide a wide variety of atmospheric variables forecasted up to 96-hours and currently feature an outer grid that covers much of western North America and the northeastern Pacific; a nested grid that covers Washington, Oregon, Idaho, Utah, much of Montana and Nevada, southern British Columbia, and northern California; and an inner grid encompassing all of Washington, Oregon, and Idaho plus the western third of Montana and the extreme northern sections of California, Nevada, and Utah, and the western third of Wyoming. A high-resolution domain is also run which covers Washington, Oregon, the western portion of Idaho, and the extreme southern 40-50 km of British Columbia.

The Texas-Louisiana regional ocean forecast system (TXLA ROFS) provides near-real time ocean forecast data to various stakeholders for different purposes, but primarily for oil spill responses. TXLA ROFS is forced by NOAA’s GFS and Global HYCOM provides open boundary conditions. It includes streamflow of 9 rivers across Texas and Louisiana including the Mississippi and Atchafalaya rivers to accurately represent the plume from the rivers. Tides are not included.

The Gulf Coast Red Tide Respiratory Forecast relies on Karenia brevis cell counts collected at individual beach locations by regional partners in Florida and Texas. Additionally, HABScope – a network of community scientists, provides supplementary monitoring data. The forecast combines Karenia brevis cell counts with forecasted wind speed and direction to predict potential respiratory irritation risk at individual beaches every 3 hours over the next 36 hours.

The California ROMS-BEC model (Regional Oceanic Modeling System coupled online to the Biogeochemical Elemental Cycling) is a coupled physical-biogeochemical oceanic model providing hindcast outputs for the period of 1997-2017 after three and half years of spin up. The model is forced offline by a 6-km resolution atmospheric Weather Research Forecast model (WRF6). The domain encompasses the entire California coast at a resolution of 1 km. ROMS-BEC is co-developed and ran at the Center of Earth System Research group at UCLA, in partnership with UW and SCCWRP.
