    • Regional Ocean Modeling System (ROMS): Western North Pacific

    Metadata Updated: August 27, 2025

    Regional Ocean Modeling System (ROMS) 7-day, 3-hourly forecast for the region surrounding the Western North Pacific at approximately 8-km resolution. Boundary conditions provided by the global, 1/12-degree (~9-km) HYbrid Coordinate Ocean Model (HYCOM). Atmospheric forcing generated by the NOAA/NCEP Global Forecast System (GFS) model for the region surrounding the Western North Pacific at approximately 25-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 5 days using all available observations to improve the model estimate of current ocean state (its nowcast) before forecasts are run. Assimilated observations are collected independently of PacIOOS and may include satellite-based sea surface temperatures from MODIS, AVHRR, or OSTIA; satellite-based sea surface height from AVISO; surface currents around Palau from CORDC High Frequency Radars (HFR), Scripps Institute of Oceanography; and in-situ water temperature and salinity profiles from ARGO floats. 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.
