Abstract. Ambient air pollution poses a major global public health risk. Lower-cost quality sensors (LCSs) are increasingly being explored as tool to understand local problems and develop effective solutions. A barrier LCS adoption is potentially larger measurement uncertainty compared reference technology. The technical performance of various LCSs has been tested in laboratory field environments, growing body literature on uses primarily focuses proof-of-concept deployments. However, few...
The benefits of monitoring ambient air pollution with instruments mounted to ground-based, moving platforms include increased spatial resolution measurements and synchronous, fast-response close road sources for emissions analyses. However, these come at the cost obtaining a suitable number repeat visits each location in order achieve reliable representative estimates desired temporal resolution. Thus, methods that maximize information content derived from limited coverage mobile are needed...
We performed more than a year of mobile, 1 Hz measurements lung-deposited surface area (LDSA, the 20–400 nm diameter particles, deposited in alveolar regions lungs) and optically assessed fine particulate matter (PM2.5), black carbon (BC), nitrogen dioxide (NO2) central London. spatially correlated these pollutants to two urban emission sources: major roadways restaurants. show that optical PM2.5 is an ineffective indicator tailpipe emissions on roadways, where we do observe statistically...
