Experimental Data Access
Operational Data Access
The NOAA Great Lakes Environmental Research Laboratory's Next Generation Great Lakes Coastal Forecasting System (GLCFS) is an experimental set of hydrodynamic computer models that predict lake circulation and other physical processes (e.g.thermal structure, ice dynamics) of the lakes and connecting channels in a real-time nowcast and forecast mode.
GLERL maintains a two-week rolling window of access to the next-generation GLCFS data. Users can access these data on our THREDDs server here, or the website links below.
If you need help getting started with plotting or extracting data from the netCDF model output, please visit the GLERL Code Gallery on GitHub for examples.
The current third generation of the GLCFS runs in near real-time at NOAA’s Great Lakes Environmental Research Laboratory (GLERL), and operationally at NOAA’s National Ocean Service (NOS) under the name Great Lakes Operational Forecast System (GLOFS). GLOFS includes the four following operational models :
Due to their operational starting dates, the data collection time period varies for each model. Several sources of operational data are available including:
