IADN and Canada’s Air Monitoring in the Great Lakes Basin program form a joint binational monitoring network that has been in operation since 1990. There are five master monitoring stations, one near each of the Great Lakes.

• Eagle Harbor on Lake Superior;
• Brule River on Lake Superior;
• Sleeping Bear Dunes on Lake Michigan;
• Sturgeon Point on Lake Erie; and
• Point Petre on Lake Ontario.

To understand better the contribution of urban sources to lake wide loadings, IADN also has two satellite stations located in Chicago and Cleveland.
