PM2.5 Open Data Portal

This Open Data API provides data access to the LASS PM2.5 project, which is a participatory sensing project for large-scale PM2.5 monitoring. The project engages citizens to participate in the PM2.5 sensing project and empowers participants to make low-cost PM2.5 sensing devices on their own. Moreover, it enables PM2.5 monitoring at a finer spatio-temporal granularity and enriches environmental data analysis by making all measurement data freely available for everyone. By 2020, the project has deployed more than 15,000 low-cost PM2.5 sensors in 58 countries, and the network is still fast growing. For more details, please visit PM2.5 Open Data Portal.
