Local Climatological Data, 1901-1962 : Hillsboro

Hillsboro is a farming and commercial center and the county seat of Montgomery County. The surrounding area is part of the Springfield Plain Physiographic Section. The topography is generally flat with broad, shallow valleys. The topography has no effect on the weather and climate of the Hillsboro area.published or submitted for publicationis peer reviewedOpe

Science for society

The Illinois State Water Survey, founded in 1895, conducts scientific research and provides service programs relating to Illinois water and atmospheric resources. ISWS is a division of the Illinois Dept. of Natural Resources, Office of Scientific Research and Analysis.This brochure briefly describes Illinois State Water Survey units and provides agency contact names with phone numbers

Global Climate Change and Illinois

The climate of Illinois is greatly affected by the state's position in the middle of the North American continent, the third largest land mass on earth. The mountains in the western part of the continent are a formidable barrier to the prevailing westerly winds that circle the globe. But flat lands in the central United States permit air movement across the Midwest from both the frozen lakes of northern Canada and the warm Gulf of Mexico. The shape, size, and surface topography of North America set the stage for Illinois' climate.published or submitted for publicationis peer reviewe

Estimated Potential Yield of Sand and Gravel Aquifers

Estimated Potential Yield of Sand and Gravel Aquifers - Taken from An Analysis of Groundwater Use to Aquifer Potential Yield in Illinois, Wehrmann, H. Allen, Sean V. Sinclair, and Timothy P. Bryant., 2003 Illinois State Water Survey, Champaign, IL, ISWS CR 2004-11. Abstract Excerpt: Proper water resource planning and management requires a firm understanding of water use and water resource availability. This report summarizes a comparison of Year 2000 groundwater withdrawals against estimated aquifer potential yields. The comparison is presented as a ratio of groundwater use (withdrawals) to groundwater yield (i.e., potential aquifer yield) on a township basis. Geographical Information System (GIS) technology was used to determine township yield ratios for three aquifer types (sand-and-gravel, shallow bedrock, and deep bedrock). This map is available online as a 24" x 36" PDF file (800k). Download a full text version of this publication: An Analysis of Groundwater Use to Aquifer Potential Yield in Illinois.Ope

Midwestern Climate Information System

The Midwestern Climate Center disseminates climate information through the Midwestern Climate Information System (MICIS). This interactive, computer-based, dial-up data source provides economically and environmentally important climate information in a timely, easy-to-access manner.published or submitted for publicationis peer reviewe

Central Analytical Laboratory

housands of precipitation samples are collected each year by the National Atmospheric Deposition Program/National Trends Network (NADP/NTN), the nation's acid rain monitoring network. A network of this size and importance requires careful, accurate laboratory analyses. Since the network's beginning in 1978, it has relied on its Central Analytical Laboratory (CAL) at the Illinois State Water Survey to fulfill its need for high-quality analyses and data.published or submitted for publicationis peer reviewe
