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.

Open this plot in a new window for comparison with other plots. Once the image is loaded up in another window, you can modify this plots parameters.

*Note: Precipitation recorded from this network is not reliable. You should use precipitation obs from the COOP network.

Departure from climatology is shown below the accumulated value.

Note: Some stations are slightly moved on the map to improve readability.
