Characterizing Vehicular Contributions to PM_2.5 in Fairbanks

This study collected measurements of PM_2.5 emissions from vehicles operating in winter conditions in Fairbanks on a dynamometer and on roads using a "plume-following vehicle". Sierra Research, FNSB, and DEC staff participated in conducting the study. Results indicate that EPA's mobile source emission models over estimate emissions from vehicles operating in Fairbanks in the winter. Information from this study was used when creating the emission inventory for the FNSB Moderate Area SIP.
