Title: Tools for Estimating Contributions of Wildland and Prescribed Fires to Air Quality in the Southern Sierra Nevada, California

Project Proposal Abstract: A comprehensive network for monitoring ambient ozone (O3) and particulate matter (PM) in the southern Sierra Nevada will be established as a joint effort between the USDA Forest Service, the National Park Service, the University of Houston and University of California in Merced. This network of passive and active monitors will allow for the estimation of spatial and temporal distributions of air pollutants resulting from urban and agricultural activities. During fire events, this network and mobile instruments will help to characterize effects of prescribed and wildland fires on the ground-level O3 and PM concentrations. Maps of estimated ambient O3 and PM concentrations will be developed with a Geostatistical Analyst model. Additionally, the BlueSky dynamic modeling system will be adapted and run for the southern Sierra Nevada conditions providing forecasts of PM concentrations resulting from forest fires. A statistical model for forecasting next day or next week O3 and PM levels (with specified precisions) will be developed based on ground monitoring data, meteorological conditions, estimated background O3 and PM distribution from geostatistical models, and predicted contributions of fires from the BlueSky model. Such forecast will be done in absence and presence of prescribed fires. Another statistical tool will be developed for evaluating and estimating the precisions of the BlueSky PM forecasts.
