Abstract
 Predicting Areas of High Diesel Particulate Matter Using Spatial Analysis Track: Climate, Weather and Atmosphere Author(s): Bryan Penfold, Steve Brown, Hilary Hafner Growing evidence suggests that inhalation exposure to diesel exhaust, including diesel particulate matter (DPM), causes acute and chronic health effects. As a result, interest in monitoring diesel exhaust has increased. Maps of emissions sources, emissions activity data, and meteorology were combined within a GIS suitability model to produce a composite map identifying regions where DPM emissions are likely to be high. The results of the GIS model were compared to the locations of existing monitoring sites in Phoenix and the spatial distribution of population. The results indicate that two existing sites are located in areas where DPM emissions are predicted to be high; however, incorporating meteorology as a factor showed that one site is located upwind of a predicted high DPM area. Consideration of population density showed high density in two areas that appear to be moderately influenced by DPM. Bryan Penfold Sonoma Technology, Inc.
