Description

Weather elements affecting the calculation of the Canadian Forest Fire Weather Index (FWI) are described. How to choose an adequate weather station site for fire danger rating observations, how to expose each weather instrument correctly, and the consequences of errors in weather data on the FWI are outlined. Weather instrument standards of accuracy and required precision in taking fire weather readings are described. Adjustment procedures are provided to users for such things as anemometers exposed in clearings too small to give representative wind speeds for danger rating calculations, and for making corrections to spring Fire Weather Indices when overwinter precipitation has been insufficient to replenish forest fuel moisture.
