Description

This report presents the equations for the new 1976 metric version of the Canadian Forest Fire Weather Index. In addition to the changes needed to accommodate metric weather data, several mathematical improvements are introduced as well. These eliminate certain anomalies in the original version, but their overall effect is light enough that no serious problems in comparing new and old indexes should arise. Also presented is a Fortran IV program showing how the equation may be processed by computer.
