An atmospheric general circulation model (AGCM) has been initialized with a 150 Tg summertime injection of smoke from post-war fires over Europe, Asia and North America. The smoke is subject to large-scale and convectice transport, dry deposition, coagulation and precipitation…

The character of most southern forest ecosystems has been shaped by fire. Indians and early settlers fired the woods for many purposes. After a period of attempted fire exclusion, foresters recognized the necessity of fire by prescription in southern pine cover types. This paper…
