The purpose of Regional Ocean Forecast System (ROFS) was to generate daily nowcasts (i.e. analysis) and short-term (of order of days) forecasts of ocean properties for the coastal ocean of the United States. The development of ROFS for the U.S. East coast began in 1991 and it was implemented as experimental real time forecasting system in August, 1993. ROFS is based on hydrodynamic, three-dimensional ocean circulation model driven driven at the ocean surface boundary by heat, moisture, and momentum fluxes provided by NCEP's NAM mesoscale atmospheric forecast model. For description of ROFS nowcast - two days forecast cycle read ROFS Description .
