Regional Hydrodynamic Model Outputs of the NOAA Operational Forecast System (OFS)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: April 12, 2026 at 09:27 PM | Dataset Last Updated: January 01, 2017 at 12:00 AM
This dataset comprises output fields from NOAA Operational Forecast System (OFS) coastal ocean models. The National Ocean Service (NOS) maintains a suite of operational high-resolution hydrodynamic nowcast/forecast systems known as Operational Forecast Systems (OFS). The OFS are implemented in critical ports, harbors, estuaries, the Great Lakes and coastal waters of the United States and provide nowcast and near-term forecast guidance (generally 48 hours) of total water level (without waves), currents, salinity, and water temperature. This dataset includes two types of outputs: (1) time series of gridded (3-dimensional) model fields at up to hourly intervals; and (2) time series of values at specific locations, generally representing observing stations located within the model domain, at up to 6-minute resolution. The format of both types of files is CF-compliant netCDF. Though the OFS models are run 4x daily, for most domains NCEI only preserves one realization of each output time slice (i.e. only the 0-5 hour forecast fields from each run cycle are preserved).
