Home > RTOFS Global model forecast documentation

The global operational Real-Time Ocean Forecast System (Global RTOFS) at the National Centers for Environmental Prediction is based on an eddy resolving 1/12° global HYCOM (HYbrid Coordinates Ocean Model) and is part of a larger national backbone capability of ocean modeling at the National Weather Service in a strong partnership with the US Navy.

The model is run once a day, completing at about 1700Z. Each run starts with a 24 hr hindcast and produces ocean surface forecasts every hour and full volume forecasts every 6 hours out to 192 hours.

RTOFS (Global) model data is available after about 1700 UTC .

Nowcast/Forecast graphics are updated the next day.
