The upgraded Lake Erie Operational Forecast System (LEOFS) was jointly developed by NOAA/National Ocean Service's (NOS) Center for Operational Oceanographic Products and Services (CO-OPS) and Office of Coast Survey (OCS), the Great Lakes Environmental Research Laboratory (GLERL), the NOAA/National Weather Service's (NWS) National Centers for Environmental Prediction (NCEP) National Central Operations (NCO), and the University of Massachusetts-Dartmouth.
The NWS and NOS work together to run LEOFS operationally on NOAA's High Performance Computing System (HPCS). By running on NOAA's HPCS, LEOFS has direct access to National Weather Service operational meteorological products that are required for reliable operations.
LEOFS uses the Finite Volume Community Ocean Model (FVCOM). LEOFS provides users with nowcast (analyses of near present) and forecast guidance of water levels, currents and water temperature out to 120 hours, four times per day.
