- Abstract
- Data from a dense network of 30 raingauge stations in each of two 37 mile square areas of northwestern Quebec are used to test how eell drought indexes calculated from single rainguage stations located in the center andin the cornersof areas, represent the average areal drought index. Data for 3 fire seasons in 1961, 1962 and 1963 indicate little difference from station to station, however, the central stations in each area proved to be slightly superior indicators of the areal drought index, being more consistent from year to year and less prone to occasional large deviations from the areal drought index. The central station in the North Area was representative of the areal drought index (within ±2 units of the Drought Index) on 91% of the observed days, and in the South Area on 8% of the observed days.
