Regional Ocean Modeling System (ROMS) 3-day, hourly forecast and 3-day, hourly hindcast for the region surrounding the Waikiki area of the island of Oahu at approximately 40-m resolution. Boundary conditions provided by the wider ROMS model for the region surrounding the south shore of the island of Oahu (roms_hiomsg) at approximately 200-m resolution. Wave forcings generated by the Simulating WAves Nearshore (SWAN) regional wave model for the island of Oahu (swan_oahu) at approximately 500-m resolution. Atmospheric forcing generated by the Weather Research and Forecasting (WRF) model for the region surrounding the island of Oahu (wrf_oa) at approximately 1.5-km resolution. Tide forcing uses the Oregon State University (OSU) Tidal Prediction Software (OTPS) TOPEX/Poseidon global inverse solution (TPXO) to derive barotropic tidal elevation and velocity. Data are assimilated over the previous 3 days using all available observations to improve the model estimate of current ocean state (its nowcast) before forecasts are run. Assimilated observations may include satellite-based sea surface temperatures from MODIS, AVHRR, or OSTIA; satellite-based sea surface height from AVISO; surface currents from PacIOOS high-frequency radios (HFR); river transport from USGS stream gauges; and in-situ water temperature and salinity profiles from ARGO floats and ocean glider autonomous underwater vehicles (AUV). While considerable effort has been made to implement all model components in a thorough, correct, and accurate manner, numerous sources of error are possible. As such, please use these data with the caution appropriate for any ocean related activity.
