Real-time Meteorological Observation Network Information Page

Objectives: Establish a network of real-time meteorological stations at exposed coastal sites around Lakes Michigan, Huron, and Erie
  • obtain observations (1-4x per hour) from these stations and make them available to NWS forecast offices and
    to the entire Great Lakes community in real-time through AWIPS/NOAAPORT
  • analyze the impact of the meteorological data obtained by this network on nowcasts and forecasts of waves and
    circulation in the Great Lakes Coastal Forecasting System
  • demonstrate the feasibility of installing and maintaining a real-time meteorological network in the Great Lakes
