KBDI Report Archives

Average Detailed Rainfall Report Archive

This is the front end for the KBDI Archives.
KBDI records as far back as three years ago today are available.

The Keetch-Byram drought index (KBDI) is a continuous reference scale for estimating the dryness of the soil and duff layers.
The range of the index is determined by assuming that there is 8 inches of moisture in a saturated soil that is readily available to the vegetation.
