    Illinois Climate Network marks 30 years of monitoring Illinois weather and soil

    Jan 31, 2019 10:45 am

    It’s been 30 years since the Illinois State Water Survey launched the Illinois Climate Network (ICN) to monitor the state’s weather and soils. The 19 ICN stations around the state collect data on wind speed and direction, air temperature, humidity, precipitation, barometric pressure, solar radiation, soil temperatures and soil moisture. Water Survey staff also calculate data on dew point, degree days, potential evapotranspiration, and temperature inversion. All of this information—an annual total of 2 million records—is used by farmers, researchers, and businesses for decision making and planning.
