1-1000 Hour Fuel Moistures
Important! In the IFTDSS GeoTIFF download of this output, values for non-burnable pixels are 0.000000 unless the GeoTIFF download was request prior to 6/24/19.
Moisture content of fuel (dead woody fuel) is the mass of water within the fuel particle expressed as a percentage of the fuel particle’s oven-dry mass.

Brief Description |
|---|---|---|
| < 1/4 | 1-Hr | Fine flashy fuels that respond quickly to weather changes. Computed from observation time temperature, humidity, and cloudiness. |
| 1/4 - 1 | 10-Hr | Computed from observation time temperature, humidity, and cloudiness. Alternatively, these can be an observed value from a standard set of "10-Hr Fuel Sticks" that are weighed as part of the fire weather observation. |
| 1 - 3 | 100-Hr | Computed from 24-hour average boundary condition composed of day length, hours of rain, and daily temperature/humidity ranges. |
| > 3 | 1000-Hr | Computed from a 7-day average boundary condition composed of day length, hours of rain, and daily temperature/humidity ranges. |
