The School of Environmental Sciences Agrometeorology group maintains two automatic weather stations that collect hourly climatic data. These weather stations are located at the Elora Research Station (ERS) and the Guelph Turfgrass Institute (GTI). Up until August 2005, the data are listed in monthly files that can be downloaded and imported into a spreadsheet for analysis. Beginning in 2006, the Elora data is posted as yearly files. This practice began in 2007 for the data from the Turfgrass Institute. Any questions can be directed to Jordan Forsyth firstname.lastname@example.org or by calling 519-824-4120 x. 52208.
