Environmental Properties for the Great Lakes
Some of the important environmental parameters used to develop the models for each of the Great Lakes are provided in the table below. Other parameters including temperature, rainfall rates, runoff rates from soils and sedimentation rates were derived from a variety of sources including the National Oceanic and Atmospheric Administration Great Lakes Research Laboratory (NOAA GLERL), Integrated Atmospheric Deposition Network (IADN), and several published papers.
