Over the past decade, there has been exponential growth in low-cost air pollution sensing
technology. While low-cost sensors can provide a path towards more accessible air quality …

Identifying and quantifying the sources and clarifying the impacts of ultrafine particles (UFP)
in the complicated urban environments are important for particle pollution control and UFP …

Previous studies have characterized spatial patterns of pollution with land use regression
(LUR) models from distributed passive or filter samplers at low temporal resolution. Large …

COVID-19-related closures offered a novel opportunity to observe and quantify the impact of
activity levels of modifiable factors on ambient air pollution in real time. We use data from a …

Low-cost NO2 sensors have been widely deployed for atmospheric sampling. While their
initial performance has been characterized, few studies have examined their long-term …

Traffic-related air pollutants are major contributors to deteriorating urban air quality and pose
a serious threat to pedestrians. From both a scientific and a regulatory standpoint, it is …

The application of low‐cost air quality monitoring networks has substantially grown over the
last few years, following the technological advances in the production of cheap and portable …

The negative health impacts of air pollution are well documented. Not as well-documented,
however, is how particulate matter varies at the hyper-local scale, and the role that proximal …

Background There is substantial interest in using networks of lower-cost air quality sensors
to characterize urban population exposure to fine particulate matter mass (PM2. 5) …

Introduction: Traditional methods to estimate exposure to PM2. 5 (particulate matter with less
than 2.5 µm in diameter) have typically relied on limited regulatory monitors and do not …
