ILLINOIS

Water and Atmospheric Resources Monitoring Program (WARM) Open map of network
The Illinois State Water Survey (ISWS) WARM collects weather data from Illinois Climate Network (ICN) weather stations, and hydrological data (shallow groundwater wells, in-stream sediment, reservoir heights and U.S. Geological Survey (USGS) stream gages (http://www.isws.illinois.edu/warm/about.asp).  The ICN network consists of 19 stations where hourly  data have been collected since 1989:  air temperature, relative humidity, wind direction and speed, solar radiation, precipitation, soil temperature (4 & 8, inches under bare soil and sod at 19 stations); soil moisture (2, 4, 8, 20, 39 & 59 inches); estimates of dew point temperature and potential evapotranspiration computed.   http://www.isws.illinois.edu/warm/datatype.asp

Cook County precipitation Network (CCPNOpen map of network
This network has collected hourly precipitation data year-round at 25 sites in Cook County since 1989, and 10-minute data since 2001. http://www.isws.illinois.edu/data/ccprecipnet/livedata.asp

Bondville Environmental and Atmospheric Research Site (BEARS) Open map of network
The BEARS site, located in rural east-central Illinois, hosts atmospheric measurement equipment from 11 projects funded variously by NOAA-Environmental Research Lab, NOAA-Atmospheric Research Lab, USDA, NASA, U.S. EPA, Illinois EPA, ISWS, the University of Colorado and the University of California at Davis.  These networks include: the National Atmospheric Deposition Program, Surface Radiation Budget Network (SURFRAD), UV-B Monitoring and Research Program, the Atmospheric Integrated Research Monitoring Network (AIRMoN-Dry), the Aerosol Robot Network, the Clean Air Status and Trends Network (CASTNET), the Interagency Monitoring of Protected Visual Environments (IMPROVE), and the Water and Atmospheric Resources Monitoring Program (WARM).

IOWA

Iowa Environmental Mesonet (IEM)  Open map of network
Hourly data from many weather networks have been collected under the umbrella of the IEM (http://mesonet.agron.iastate.edu/sites/locate.php), including ASOS/AWOS Networks, the Roadway Weather Information System (RWIS),  precipitation  data from the Data Collection Platforms (DCPs) and the Community Collaborative Rain, Hail and Snow (CoCoRaHS) networks. Data from two other networks also are accessed through this site, the Iowa State University Ag Climate Data (ISU-Ag) and the Soil Climate Atlas Network (SCAN). The ISU-Ag collects air temperature, relative humidity, wind direction and speed, precipitation, solar radiation, soil temperature (4 inches), and estimated potential evapotranspiration at 11 stations, some starting in 1988. http://mesonet.agron.iastate.edu/agclimate/info.phtml

These data are included in the Automated Weather Data Network archived at the High Plains Regional Climate Center: http://www.hprcc.unl.edu/awdn/

SCAN, Open map of network operated by the National Water and Climate Center, measures air temperature, relative humidity, wind direction and speed, precipitation, solar radiation, soil temperature (2, 4, 8, 20, 40  inches), soil moisture (2, 4, 8, 20, 40 inches) and estimates potential evapotranspiration at  5 stations beginning in 2000.  In addition, barometric pressure and dew point temperature are available from the SCAN sites. http://mesonet.agron.iastate.edu/scan/

MICHIGAN

Enviro-Weather Automated Weather Station Network  Open map of network
The Michigan Enviro-Weather Automated Weather Station Network has operated since 1992 and serves the state's agriculture and natural resource industries. Following a recent collaborative agreement with the University of Wisconsin, the network has expanded into neighboring sections of Wisconsin. Temperature (5 ft), relative humidity (5 ft), wind direction and speed (10 ft), precipitation, solar radiation, soil temperature (2, 4  inches), soil moisture (4, 10 inches), leaf wetness (39 inches), and estimated potential evapotranspiration at 75 sites.  Data are collected every 60 minutes during the growing season (April-October) and every 3 hours during the off season and made available at daily, hourly, and 5-minute reporting intervals.    http://www.agweather.geo.msu.edu/mawn/

MINNESOTA

Regularly updated climate information are available from a variety of sources (http://climate.umn.edu/doc/agwx.htm).  Ten North Dakota Automated Weather Network (NDAWN) stations are located in Minnesota (http://ndawn.ndsu.nodak.edu and http://www.hprcc.unl.edu/awdn/). Open map of network  These include soil temperature, solar radiation, computed evapotranspiration, as well as standard meteorological variables. Minnesota's Department of Agriculture has wired soil temperature probes at the 6 inch level to ten stream gauging DCP/HADS stations (http://gis.mda.state.mn.us/maps/csgsoil.htm).

Southern Research and Outreach Center (SROC): Open map of network measures hourly air temperature, relative humidity, wind direction and speed, solar radiation, precipitation, and evaporation, as well as soil temperature (2, 4, 8, 20 and 40 inches): http://climate.umn.edu/doc/waseca.htm
and soil moisture at Waseca MN (2000-2011): http://climate.umn.edu/img/soil_moisture/wassm2011.gif.

Southwest Research and Outreach Center (SWROC): Open map of network measures air temperature, precipitation, soil temperature (2, 4, and 8 inches)

Minnesota Volunteer Precipitation Observing Program (MNgage): Open map of network this high spatial-density precipitation volunteer observing program began in the late 1960s in the Twin Cities and gradually expanded across Minnesota in the 1970s. The network is based at the Minnesota State Climatology Office, with the number of warm-season observers remaining steady at 1,400 for the past twenty years. Daily precipitation measurements are reported both online and by use of hard copy forms.    http://climate.umn.edu/HIDENsityEdit/HIDENweb.htm
