19TH CENTURY FORTS & VOLUNTARY OBSERVERS DATABASE BUILD PROJECT

The Climate Database Modernization Program (CDMP) is working to preserve and place on-line a wide range of observations about the climate from the last three centuries.  Three web tools are currently available as well as histories of selected stations.

WEST NILE VIRUS MOSQUITO CROSSOVER DATES

The white-spotted mosquito and the northern house mosquito are believed to maintain the natural transmission cycle of West Nile Virus between birds and mosquitoes in Illinois. Two types of climate models have been developed to provide an estimate of the likely date where the northern house mosquito begins to become the dominant species, and thus when the risk of WNV to horses, humans, and other wildlife is likely to increase.

The information provided here is based on recent research conducted by scientists at the Midwestern Regional Climate Center, Illinois State Water Survey and the Illinois Natural History Survey in association with the National Climatic Data Center.
