Growing Season Maps

This application will plot an accumulated variable for a time period of your selection. Data is based on the automated sensors from the ISU AG Climate network. A similiar application exists based on the COOP network data, which is of higher quality for temperature and precipitation.

We are currently working through some data quality issues with the new ISU Soil Moisture network for 2014. Please use care when using these values and graphics!
