The Real-Time Air Quality Billboard Displays project involves large electronic screens placed in public spaces that show the live air quality in specific locations, measured by local air quality sensors. These sensors detect particulate matter and air pollution compounds, providing highly localized data, which is important due to the significant variability in air quality from one city block to another.

The billboards use ambient messaging and color grading, presenting air quality information in real time through a feedback loop. By utilizing behavioral science research, the color-coded data subtly signals people to modify their behavior based on the current air quality, fostering greater awareness and encouraging actions to reduce exposure or emissions. This innovative display system enhances public awareness of environmental health in everyday spaces.
