The effects of meteorological phenomena upon forest produc- tivity and forestry operations have been of concern for many years. With the evolution of system-level studies of forest eco- system structure and function in the International Biological Program and elsewhere, more fundamental interactions between forest ecosystems and the atmosphere received scientific atten- tion but the emphasis on meteorological and climatological effects on forest processes remained. More recently, as recogni- tion has developed of potential and actual problems associated with the atmospheric transport,...
