Historical IDF Curves
Training information on the use of Historical IDF Curves may be found in the Learning Zone.
For indices not included in the pre-calculated variable list, the Analyze page can be used to create custom indices, such as Days with a Freeze-Thaw cycle.
Further information on using climate data or selecting a relevant historical dataset can be found in the Learning Zone.
