Receptor modeling of transport of acidic air pollutants and oxidants to forested regions in the Sierra Nevada. Final report
The major source area of acidic species and their precursors which has the potential for impact in the Sierra Nevada is the San Joaquin Valley (SJV). During the summer of 1990, the San Joaquin Valley Air Quality Study (SJVAQS) and Atmospheric Utility Signatures, Predictions and Experiments (AUSPEX) studies, two major, integrated field studies, were performed. These studies provided a basis for extending the knowledge of air pollution effects to regions outside the study area which are affected by emissions from that region. There were two main facets to the study. The first involved field measurements that are required as input for the receptor modeling task. The second involved the application of receptor models to apportion sources of atmospheric acidity. Sites included SJVAQS/AUSPEX sites at Sequoia and Yosemite, a site in the vicinity of Tehachapi, and a site on the western slope of the northern Sierra Nevada near Lake Tahoe (Blodgett Experimental Forest). Measurements of gaseous and fine particulate inorganic and organic acidic species were made on 14 days corresponding to the SJVAQS/AUSPEX intensive measurement days.
