An automated station moored in Lake Michigan near Michigan City, Indiana, collects real-time meteorological and oceanographic data. This data typically includes wind speed and direction, wave height and period, air and water temperature, atmospheric pressure, and sometimes water current speed and direction. These stations, often anchored to the lakebed, transmit data via satellite or radio to agencies like the National Oceanic and Atmospheric Administration (NOAA) and are often part of larger networks providing comprehensive coverage across the Great Lakes.
Real-time data from these strategically placed instruments supports a wide range of activities. Mariners rely on this information for safe navigation, while weather forecasters use it to improve prediction accuracy, particularly for lake-effect snow and other localized weather phenomena. Researchers leverage the data for studies related to climate change, water quality, and ecosystem health. The continuous monitoring also enhances safety for recreational boaters and other users of the lake. Historical data collected over time contributes to a deeper understanding of long-term trends and patterns in the lake environment.
