Journal ArticleDOI
Commuter exposure to PM2.5, BC, and UFP in six common transport microenvironments in Sacramento, California
TL;DR: In this article, the authors measured concentrations of fine particle matter (PM 2.5 ), black carbon (BC), and ultrafine particles (UFP) for 161 commutes between 2014 and November 2015 in Sacramento, CA.
Journal ArticleDOI
Mobile sampling of methane emissions from natural gas well pads in California
Xiaochi Zhou,Seungju Yoon,Steve Mara,Matthias Falk,T. Kuwayama,Travis Tran,Lucy Cheadle,Jim Nyarady,Bart E. Croes,Elizabeth Scheehle,Jorn D. Herner,A. Vijayan +11 more
TL;DR: In this article, a mobile measurement system combined with a source characterization model was designed to measure methane emissions from non-associated (i.e., produced without crude oil extraction) natural gas (NG) well pads in California.
Journal ArticleDOI
Investigating the real-world emission characteristics of light-duty gasoline vehicles and their relationship to local socioeconomic conditions in three communities in Los Angeles, California
TL;DR: The study observed a significant reduction in vehicle emissions for all measured pollutants when compared to an earlier study in Wilmington, CA, and found a higher prevalence of high-emitting vehicles in low-socioeconomic-status communities.
Journal ArticleDOI

TL;DR: This study provides a thorough multi-year evaluation of the emissions inventory using independent atmospheric measurements, and investigates the utility of a complementary multi-platform approach in understanding the spatial and temporal patterns of CH4 emissions in the state, and identifies opportunities for the expansion and applications of the monitoring network.
