Expanding degree day calculator offers website-precise climate information

CHAMPAIGN, Ill., 9/two/20: The Illinois State Water Survey (ISWS) increasing degree day (GDD) calculator is updated day-to-day by means of nearby climate stations for customers to calculate projections on crop improvement and maturity particularly for their place.

The calculator tallies heat accumulation all through the increasing season, comparing day-to-day maximum and minimum temperatures with a base temperature for each and every crop, above which crops will create and mature. Day-to-day temperatures derive from Illinois Climate Network stations across the state.

The reduced threshold is 50 degrees for corn and 40 degrees for specialty crops. The higher threshold for corn is 86 degrees. The GDD values are calculated from Jan. 1 and applied to evaluate the progress of a increasing season to the extended-term typical.

Variations happen every single year, and this year, the heat index for the GDD is operating slightly ahead of some preceding years, according to Jennie Atkins, plan manager of the ISWS Water and Atmospheric Sources Monitoring Plan (WARM). Projections of a single and two weeks can be applied late in the season, for instance, to assistance establish plant development stages and thereby give much more info in thinking of when to harvest crops.

The GDD calculator is accessible on the ISWS WARM site , which also offers a state map of increasing degree days. The WARM website needs customers to register, but the info is absolutely free.

For a regional view of GDD, access the Midwest map on the Midwestern Regional Climate Center site.
