Important Notice:

The Hancock and Arlington stations were operated by Michigan State University Enviroweather Service between 2017 and 2023 and data for that period can be downloaded from their website.

From 2023-present, data from the Hancock and Arlington stations, as well as some additional stations in Wisconsin, are available from the Wisconsin Environmental Mesonet (WiscoNet) website.

List of stations, their geographic locations, and the operational dates.

	Arlington and Hancock stations have a continuous record in the daily and the "hourly and half-hourly" tables; hourly prior to 1999, half-hourly subsequently. Some of the other stations used "half-hourly", others "hourly". Not all stations collected each type of data.

Clearing all checkboxes is the same as checking them all (you'll get everything).
