A Method to Initialize the Keetch-Byram Drought Index
The 1988 National Fire Danger Rating System implements the Keetch-Byram Drought Index. This index is output both as an estimator of drought in its own right and is used to modify fire danger calculations to account for deep drying of dead vegetation and duff. A method initializes this index for those fire danger rating stations that do not run the National Fire Danger Rating System all year long. West J. Appl. For. 8(4)109-115.
