From the text: 'In 1959 Williams published a method of calculating the fire season severity rating, an integrated measure of fire weather over the whole season. Being based solely on the daily fire danger index (1956 type), it could be used as an objective yardstick for comparing fire weather from year to year or from site to site within any region using the same danger tables. The seasonal severity rating (SSR) is essentially a weighted average of the daily danger indexes in the old 16-point scale. The weighting factors were developed from 2-minute test fires in jack pine, using a combination of fire perimeter and drought index to represent severity Thus each day can be assumed to have its individual daily severity rating (DSR), and a severity rating can be calculated for any desired period such as a week or a month.'
