Pandora Project is an investigation into the sociotechnical, spatial and political dynamics of air pollution data monitoring in urban spaces. This research leverages two existing and semi-open source technologies to imagine an alternative mode for engaging with open environmental data. These technologies are: 1) Niantic Lightship Augmented Reality (AR) Developer Kit, which has been utilized to build participatory mobile AR games, such as Pokémon GO, and was recently opened to the public; and 2) PurpleAir, which consists of low-cost and high-caliber indoor/outdoor air quality sensing kits connected to open access API and a browser-based map for empowering citizen scientists. Combining these scalable yet niche platforms, Pandora Project aims to explore the affordances and limitations of exploratory and participatory methods for closing air pollution data and knowledge gaps. Pandora Project is in the research and development phase for future deployment in various cities, starting with Los Angeles, a city with severe air pollution issues, and Miami, a city with severe water issues.
