Special Notice

To be consistent and standardized for all NOS OFS, the GBOFS model output file names will be changed on January 26, 2011. The new file names will be:

nos.gbofs.stations.nowcast.YYYYMMDD.tHHz.nc
nos.gbofs.stations.forecast.YYYYMMDD.tHHz.nc
nos.gbofs_hsc.stations.nowcast.YYYYMMDD.tHHz.nc
nos.gbofs_hsc.stations.forecast.YYYYMMDD.tHHz.nc
nos.gbofs.fields.nowcast.YYYYMMDD.tHHz.nc
nos.gbofs.fields.forecast.YYYYMMDD.tHHz.nc
nos.gbofs_hsc.fields.nowcast.YYYYMMDD.tHHz.nc
nos.gbofs_hsc.fields.forecast.YYYYMMDD.tHHz.nc

YYYY is year; MM is month, DD is date, HH is cycle
Please update your scripts accordingly, if you automatically download GBOFS model outputs.

On June 30, 2004, ship traffic in Galveston Bay, Texas, gained a new tool to assist in safe navigation. The Galveston Bay Operational Forecast System (GBOFS), created by NOAA's National Ocean Service, provides mariners, port managers and emergency response teams with present and future conditions of water levels, currents, temperature and salinity.

GBOFS "nowcast" (for present conditions) and "forecast" (for future conditions) products are generated by a three-dimensional hydrodynamic model that uses real-time and forecast data to predict this information at thousands of locations throughout Galveston Bay. The information GBOFS provides assists port managers and shippers in making decisions regarding maximum tonnage and passage times without compromising safety. For more information, click here.

Disclaimer:
The Galveston Bay Operational Forecast System (GBOFS) 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 Galveston Bay. GBOFS uses a numerical hydrodynamic model to generate the nowcast and forecast information; therefore, they should be considered as model-generated nowcast and forecast guidance.
