An experimental forecasting system for the inner shelf circulations around Pt. Sal, California, was 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).

The system will be operational from September 1 to 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.
