Implication of weather patterns in the regulation of oxidant air pollution stress on forest vegetation. [Oxidant injury was compared in Pinus ponderosa, Pinus jeffrey; and Quercus kelloggii]
In this study several measures of ozone dose have been compared with each day-class or meteorological pattern and the effects of various sequences of day-classes on ozone concentrations have been investigated for 361 days during the May through October periods of 1974 and 1975 at the Sky Forest monitoring station near Los Angeles. The effects of day-class on oxidant concentrations observed at two other higher elevation stations located 12 and 24 kilometers east of Sky Forest were compared. The accumulated seasonal ozone doses and prevailing meteorological patterns of 1974 and 1975 were compared with the amount of injury to foliage of ponderosa pine (Pinus ponderosa Laws), Jeffrey pine (Pinus jeffreyi Grev. and Balf.), and black oak (Quercus Kelloggii Newb.).
