Local Weather and Climate Data

Miami University has collected weather and atmospheric chemistry data for the past 38 years, permitting Miami students and faculty to develop critical insights into the effects of changing climate on ecological systems. These data are collected by sensors at two locations, Miami's Ecology Research Center (ERC) and more recently (since 2010) with sensors operated by Miami's Center for Aquatic and Watershed Sciences (CAWS) on Acton Lake in nearby Hueston Woods State Park. Data files have been compiled containing all of the weather data available to date from these stations and are available below. For questions or inquiries about more recent data, see the contacts for each site.

Prior to downloading data, please assist us by completing this very brief survey to help us gather information on how these data are used.

Ecology Research Center Weather Data

The ERC weather station is managed locally by the Institute for the Environment and Sustainability (IES). It is funded by the U.S. Geological Survey and the U.S. Environmental Protection Agency, and serves the National Atmospheric Deposition Program/National Trends Network (NADP/NTN) in precipitation chemistry, the Clean Air Status and Trends Network (CASTNET) in air quality, and the National Oceanic and Atmospheric Administration's (NOAA) weather service.

Weather data have been collected over the past 38 years by various entities. We have compiled these data to provide consistent formatting for measurements of a single variable. The files are archived in Miami University's Scholarly Commons: Ecology Research Center Weather Data Sets. Data files are updated annually. Dates following each link indicate the date range contained in the data file. For more current data please contact us.

Original Data Sources

The above data files were compiled with data from the following sources.

Acton Lake Weather Data

Since 2010, weather data have been collected by a station managed by Miami University's Center for Aquatic and Watershed Sciences on Acton Lake (map) in Oxford, Ohio. This data set includes 15-minute interval measurements of light (photosynthetically active radiation), wind direction, wind speed, air temperature, relative humidity, barometric pressure, precipitation, lake level, and water temperature.
