1. Retention period change - Only the most recent 31 days of OFS output files will be available on CO-OPS THREDDS.
2. File structure changes - To improve THREDDS performance related to file access and data aggregation
All model nowcast and forecast information is based on a hydrodynamic model and should be considered as computer-generated nowcast and forecast guidance.
Wind Forecast Guidance
The surface wind animation depicts predicted hourly surface (33 ft [10m] above the water) winds for the next 48 hours based on weather model forecast guidance from the NOAA/NWS North American Mesoscale (NAM) Model or the Global Forecast System (GFS), if guidance from the NAM Model is not available. The hourly wind fields are created by spatially and temporally interpolating the NWS wind forecast guidance onto the TBOFS model grid. The original spatial and temporal resolutions of the NAM Model wind forecast guidance are 7.5 miles (12 km) and 3 hours, respectively. These interpolated wind fields are used by TBOFS's forecast cycle to generate oceanographic forecast guidance. The original wind products can be seen at the NWS/National Centers for Environmental Prediction web page.
