An experimental forecasting system for the inner shelf circulations around Pt. Sal, California, has been implemented using a multi-scale nesting configuration of the Regional Ocean Modeling System (ROMS) and the Simulating WAves Nearshore (SWAN) models, which are integrated in the coupled-Ocean-Atmosphere-Wave- Sediment Transport Modeling System (COAWST). You can access the forecasts here 

The system became operational on September 1, 2017 and will continue to generate daily forecasts until November 30, 2017 to assist the observational campaigns and in situ data collection of the Office of Naval Research (ONR) Inner Shelf Dynamics DRI field experiment. The forecast of ocean conditions are conducted daily through the downscaling of several nested COAWST simulation grids (3km -> 1km-> 600m -> 200m), each forced with the COAMPS 2-days atmospheric forecasts at hourly resolution. Data assimilation is performed in the atmospheric forecasts, but not in the ocean simulations. 

From this Forecast Portal you will be able to do the following:

  • Watch animations of a 2-day forecast (click on the “LATEST” tab)
  • Watch animations of the archived forecasts (click on the “HISTORY” tab)
  • Download individual 2-day forecast netcdf file for both the ocean and the atmosphere (click on the “OCEAN” or “ATMOSPHERE” tab). 

We will continue to post updates and codes on this website as they become available.
