Run Option Notes
Maximum reliable effective wind speed limit is imposed [SURFACE]. | Calculations are for the specified spread directions [SURFACE]. | Fireline intensity, flame length, and spread distance are always for the direction of the spread calculations [SURFACE]. | Wind and spread directions are degrees clockwise from upslope [SURFACE]. | Wind is blowing upslope [SURFACE]. |
