St. John's River Operational Forecast System (SJROFS)

Notice of directory structure change on the NODD S3 bucket

The NODD AWS cloud is used to disseminate model outputs from National Ocean Service's operational forecast systems (OFS).

  • As of January 1, 2025, the new directory structure will be: /OFS/netcdf/YYYY/MM/DD, where
    • OFS refers to the name of the model (e.g. cbofs, ciofs, dbofs, gomofs, leofs, lmhofs, loofs, lsofs, ngofs2, sfbofs, sscofs, tbofs, wcofs)
    • YYYY refers to the year of the model run
    • MM refers to the month of the model run
    • DD refers to the day of the model run
  • The new directory structure will improve performance while accessing the model outputs.

Starting November 20, 2024, model output files will be available in the current and new directory structures. The current file directory structure is: OFS/netcdf/YYYYMM, where one single folder usually contains over 7000 files and a large amount of memory is required for the THREDDS applications.

The current directory and new structures will co-exist until January 1, 2025, when the current directory structure will be decommissioned.

On October 1, 2005, NOAA's National Ocean Service (NOS) inaugurated the St. John's River Operational Forecast System (SJROFS). This system provides the maritime community with improved short-term predictions of water levels and currents in St. John's River.

SJROFS is a CO-OPS project aimed at providing improved predictions of water levels and currents in St. John's River. The objective of SJROFS is to produce hourly nowcasts and four times daily forecasts of total water level and current velocity in the River to be used by the commercial and recreational maritime community. SJROFS will provide important benefits to the local maritime community. SJROFS nowcasts and forecasts will provide an increased margin of safety and maximize the efficiency of maritime commerce throughout the Bay. SJROFS became continuously operational on September 30, 2005. SJROFS is a NOS joint project combining the efforts of CO-OPS and CSDL. For more information, click here.

Disclaimer:
The St. John's River Operational Forecast System (SJROFS) has been implemented by NOAA's National Ocean Service (NOS) to provide the maritime user community with short-term predictions of water levels, water currents, water temperatures and salinity of the St. John's River. SJROFS uses a numerical hydrodynamic model to generate the nowcast and forecast information; therefore, they should be considered as model-generated nowcast and forecast guidance. For more detailed information related to the OFS disclaimer, please visit at the Disclaimers web page.

During extreme weather conditions, water level forecast guidance data are released for public utility and should be used with appropriate caution.
