TLDR
This work equipped Google Street View vehicles with a fast-response pollution measurement platform and repeatedly sampled every street in a 30-km2 area of Oakland, CA, developing the largest urban air quality data set of its type, revealing stable, persistent pollution patterns with surprisingly sharp small-scale variability attributable to local sources.Abstract:
Air pollution affects billions of people worldwide, yet ambient pollution measurements are limited for much of the world Urban air pollution concentrations vary sharply over short distances (≪1 km) owing to unevenly distributed emission sources, dilution, and physicochemical transformations Accordingly, even where present, conventional fixed-site pollution monitoring methods lack the spatial resolution needed to characterize heterogeneous human exposures and localized pollution hotspots Here, we demonstrate a measurement approach to reveal urban air pollution patterns at 4–5 orders of magnitude greater spatial precision than possible with current central-site ambient monitoring We equipped Google Street View vehicles with a fast-response pollution measurement platform and repeatedly sampled every street in a 30-km2 area of Oakland, CA, developing the largest urban air quality data set of its type Resulting maps of annual daytime NO, NO2, and black carbon at 30 m-scale reveal stable, persistent pollutread more

Mapping urban air quality using mobile sampling with low-cost sensors and machine learning in Seoul, South Korea
Chris C. Lim,Ho Kim,M J Ruzmyn Vilcassim,George D. Thurston,Terry Gordon,Lung Chi Chen,Kiyoung Lee,Michael Heimbinder,Sun-Young Kim +8 more
TL;DR: The high R2 values suggest that study designs employing mobile sampling in conjunction with multiple low-cost air quality monitors could be applied to characterize urban street-level air quality with high spatial resolution, and that machine learning models could further improve model performance.
