The NOAA Great Lakes Coastal Forecasting System is a numerical model that calculates waves, currents and temperatures for each of the Great Lakes. The GLCFS Nowcast, run four times per day, provides estimates of conditions at the time the model was run. The GLCFS Forecast runs twice per day and provides a prediction of conditions 60 hours into the future. 

Two sets of model results are created during each run, one defining conditions on the surface (two-dimensional) and one that defines circulation within the lake (three-dimensional).

The Point Query tool provides quick access to Great Lakes Coastal Forecasting System (GLCFS) input data and model output for a given location and time period.

 

The GLCFS Nowcast and Forecast 2d model results include 11 variables:

Longitude in degrees north
Latitude in degrees east
Bathymetry depth in meters
Sigma value for each node
Time as UTC in seconds since 1/1/1070
Height above model sea level in meters
Eastward water velocity at surface in meters/second
Northward water velocity at surface in meters/second
Significant wave height in meters
Wave direction in degrees
Wave period in seconds

The GLCFS Nowcast and Forecast 3d model results include 10 variables:

Longitude in degrees north
Latitude in degrees east
Bathymetry depth in meters
Depth for each node in meters
Sigma value for each node
Time as UTC in seconds since 1/1/1970
Water temperature in degrees Celsius
Eastward Current velocity in meters/second
Northward current velocity in meters/second
Height above model sea level in meters

GLCFS data for the current calendar year is updated on the GLOS THREDDS server (TDS) after each run of the model. Archives of Nowcast results are created for each completed calendar year beginning with 2006. Use the links below to connect with the individual TDS dataset pages:
