City of Ann ArborHourly air quality data collected by the city. The dataset begins in 2022 with data from a few stations that used AQMesh-brand sensors. Then it switches over to a few Clarity-brand sensors, and finally expands to ten Clarity stations. We have combined the two datasets into a single one here. You can use the "vendor" column to differentiate. The city's Air Quality Dashboard visualizes this data; we are also making it available here for further exploration.air-quality-sensor-dataengAnn Arbor Data CatalogPublicEnvironmentAir Quality Sensor DataDatasetsMichigan--Ann ArborMichiganLast Modified: 2026-05-29
