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.
Water Temperature Forecast Guidance
This water temperature animation depicts forecasted hourly surface water temperature for the next 30 hours. The hourly water temperature fields were created by spatially and temporally interpolating wind forecast guidance from the National Weather Service's operational NAM atmospheric forecast model. These hourly water temperature fields were used by LOOFS' hydrodynamic model to generate oceanographic forecast guidance for the Lake Ontario out to 30 hours.
