NOAA's National Ocean Service (NOS) has developed a Cook Inlet Operational Forecast System (CIOFS). CIOFS is based on a three-dimensional ROMS model that runs on NOAA's High Performance Computers (HPC). CIOFS provides water level, currents, water temperature and salinity nowcast and forecast guidance as well as interpolated winds from National Weather Service products. CIOFS runs four times per day and generates 6-hour nowcasts and 48-hour forecast guidance. CIOFS products include time series graphics at station locations and aerial animations of the whole Cook Inlet for all five parameters (wind, water level, currents, temperature and salinity).
