From the introduction letter ... 'This publication deals with fire, a significant force in the forest environment. Depending upon land management objectives for a specific area, plus a host of environmental variables, fire will sometimes be an enemy, at times a friend, and…

Potential temperature analysis supplies needed information that is not obtainable by other methods of graphical analysis. Terrain surface maps and large-scale cross sections are constructed by using data from weather stations, raobs, and aircraft soundings. Interpretation of the…

The combustion products (smoke) from forest wildfires or prescribed burns are often considered on a par with any other emission that might affect air quality. But enough is known about smoke from woody fuels to indicate that its importance is limited almost entirely to…

The benefits from fire use - including hazard reduction, silvicultural manipulation, pathogen control, and nutrient recycling - might be forfeited by public reaction to smoke, whether harmful or not. Generally, the public desires alternatives to burning, but might accept fire if…

From the text...”Extinguishing forest fires must be done urgently, in most cases, using whatever tools at hand, with little time to employ mechanical methods. Making matters worse, location of the fire cannot be foreseen, nor such factors as wind direction and velocity. Passive…
