[PDF][PDF] Challenges in Urban Air Quality Data Visualization
Poor air quality (AQ) is one of the most important challenges of increased urbanization.
Recent advances in sensing technology have brought low-cost, real-time AQ sensing to
cities around the globe [4, 9]. Many of these sensors measure fine-particulate matter (PM2.
5)—particles with diameters smaller than 2.5 microns—which has the greatest adverse effect
on health [1, 5, 7]. Salt Lake City has a diverse set of PM2. 5 sensor networks, including low-
cost sensor networks supported by grassroots organizations [6] and government-run …

Many of these sensors measure fine-particulate matter (PM2. 5)—particles with diameters smaller than 2.5 microns—which has the greatest adverse effect on health [1, 5, 7]. Salt Lake City has a diverse set of PM2. 5 sensor networks, including low-cost sensor networks supported by grassroots organizations [6] and government-run networks of high-quality, gold-standard sensors, to measure PM2. 5. Currently, the city has no system that unifies all these sensor measurements of diverse sources to provide a comprehensive estimate of PM2. 5 levels for its residents [2, 8].
