Air Quality History
This dataset contains quality assured and DOEE-certified air quality data collected from the District’s five air monitoring network sites. The dataset covers a three-year period and includes hourly concentration data points from the Environmental Protection Agency (EPA)’s criteria pollutants, air toxics, and speciation. It also includes hourly surface meteorology data points. The District of Columbia is providing this data for a rolling 3-year period when data become available from the EPA. For complete history of data, visit the EPA Air Quality System API at aqs.epa.gov/aqsweb/documents/data_api.html
