Table 4 Fire behavior model runs versus observed results at the 1997 Magitchlie Creek Experimental Fire study area, Innoko National Wildlife Refuge, Alaska, USA. Two-meter winds were adjusted to 11.8 km h−1 at 10 m above ground using the inverse of the 0.7 WAF. N/A refers to data that is not produced by the fire behavior modeling system tested
