Great Lakes Buoy Meteorological and Oceanographic Measurements 2015-2020

Grand Marais Buoy 45172 in the Great Lakes region collected oceanographic and surface meteorological data from July 2015 to October 2020. Northern Michigan University gathered the data, which was assembled by the Great Lakes Observing System (GLOS) and submitted to NOAA's NCEI. The dataset follows CF and ACDD metadata conventions and was updated monthly during its operational period.

Use Cases

• Modeling lake temperature dynamics using water temperature time-series data.
• Analyzing wind patterns and their effect on wave height using wind speed/direction and wave measurements.
• Correlating atmospheric pressure and air temperature readings with seasonal water current data.
• Studying long-term trends in relative humidity and water conductivity for climate change impact assessments.

Strengths

• Over 5 years of continuous temporal coverage from 2015-07-09 to 2020-10-05.
• Data collected from a fixed, in-situ moored station ensuring consistent geographic location.
• Adheres to standardized Climate and Forecast (CF) and ACDD metadata conventions.
• Monthly updates were performed during the collection period, ensuring regular data integration.

Limitations

• Specific sample size, row count, and measurement frequency are unknown.
• Data collection ended in October 2020, limiting analysis of recent conditions.
• Geographic scope is limited to a single buoy location in the Great Lakes.
