Daily datasets
Description: Fuel moisture represents the dead fuel moisture content of 1000-hour fuel and is calculated based on temperature, relative air humidity, cloud cover, snow cover, and precipitation. The method of calculation is based on the NFDRS basic equations (Cohen & Deeming, 1985). The provided fuel moisture values are calculated daily from the maximum daily temperature and the minimum relative humidity to represent the daily “worst-case scenario”. Calculated values typically range from 1% to 35% with ignitions generally occurring when values drop below 15%. As fuel moisture decreases below 15%, the fire danger increases. Values below 6% are of great concern with a possible extreme fire behavior.
