Daily Data Request Form

This interface allows the download of daily summary data from the legacy ISU AgClimate Network sites. Data for some of these sites exists back till 1986 until they all were removed in 2014. In general, the precipitation data is of poor quality and should not be used. Please see the NWS COOP download page for high quality daily precipitation data. If you are looking for hourly data from this network, see this page.
