About The Illinois State Water Survey

Bondville Environmental and Atmospheric Research Site

For decades, the Illinois State Water Survey has conducted research and monitoring activities on a University of Illinois Foundation farm four miles south of Bondville in Champaign County. These activities include evaluation and application of equipment and methods to measure climate, meteorological, precipitation, and air quality parameters, including monitoring of:

  • basic air quality (sulfur dioxide, ozone, particulate, organics)
  • precipitation chemistry (major ions and cations, mercury, event based longer term)
  • long-term climate (a long term National Weather Service site)
  • on-site meteorology (wind velocity, air and soil temperatures, dew points, pressure, radiation, etc.)
  • atmospheric visibility
  • solar physics
  • continuous particulate monitoring using chromatographic methods

For information about data availability, or the use of the Bondville Environmental and Atmospheric Research Site (BEARS) for a research project, contact heal@isws.illinois.edu.

The site location and facilities provide atmospheric scientists with a unique and near ideal location for environmental measurements and sample collection. ISWS scientists and numerous colleagues from other organizations use the site for a variety of research projects: 

  • Water and Atmospheric Resources Monitoring Program (WARM): Observing meteorology, databases of Illinois climate data, monthly summaries and databases of Illinois climate data from 20 stations, flow and sediment load information for 26 Illinois gauging stations
  • Aerosol Monitoring - Earth System Research Laboratory (ESRL): Measuring baseline aerosol optical properties to determine average conditions and trends, also to enable calculation of direct aerosol climate forcing.
  • Surface Radiation Budget Network (SURFRAD): Continuous, long-term measurements of the surface radiation budget over the United States. Up and down direct and diffuse solar, photosynthetically active radiation, UVB, spectral solar, and meteorology.
  • UV-B Monitoring and Research Program: Geographical distribution and temporal trends of UVB (ultraviolet -B) radiation in the United States, measuring UV, UV-B, and photosynthetically active radiation.
  • Aerosol Robotic Network (AERONET): Long-term measurements of sky radiance to estimate aerosol phase function, size distribution and aerosol optical thickness.
  • Clean Air Status and Trends Network (CASTNET), EPA: Long-term measurements of atmospheric gases and aerosols for dry deposition calculations measures filter-based major ions, trace metals and carbon, and meteorology.
  • Interagency Monitoring of Protected Visual Environments (IMPROVE): Long-term monitoring program to establish the current visibility conditions, track changes in visibility and determine causal mechanism for the visibility impairment in the National Parks and Wilderness Areas. Measures bi-weekly filter-based particulate chemistry, optical adsorption, multiple elements, etc.
  • State of Illinois - Rural Particulate Monitoring: Federal Reference Method 6-day PM2.5 monitoring
  • Semi-Continuous Monitoring of Gases and Particulates (GPIC): Semi-continuous monitoring of particulate nitrates, sulfates, ammonium, etc.; and gaseous sulfur dioxide, nitric acid, and ammonia, etc.
