# The METRAQ air quality dataset

This is the official dataset repository for the METRAQ air quality dataset collected from the Open Data Portal of the City Council of Madrid (Spain) that collects air quality data since 2001, meteorological data since 2015 and traffic data since 2019, and has been curated to offer a reliable source. Besides, the intersection of these three data sources spans 6 years.
