The states of Minnesota, Wisconsin, Illinois, Michigan, Ohio, and New York have approximately forty-one data collection stations. NDBC also deploys drifting buoys. The real-time data is often incorporated into other observing system networks on a regional or local basis. The Great Lakes waters and shorelines have approximately eight moored buoys and eleven C-MAN stations. Approximately 29 sites currently collect data for this program, with eight stations providing near real-time information online.
Historical data is available online for all of the data collection sites.
