Air quality - ATMO index from 2021

Dataset allows to determine the number of days when the air quality is considered to be "good" to "extremely bad", based on the new ATMO index as of January 1, 2021.The ATMO index was revised and adopted by the Ministry of Ecological Transition on January 1, 2021. The ATMO index incorporates the main regulated air pollutants, tracers of transport, urban and industrial activities PM10, PM2.5, nitrogen dioxide, ozone, sulfur dioxide.It comes in six qualifiers defined according to different classes for these five pollutants: "good", "medium", "degraded", "bad", "very bad", "extremely bad".For each pollutant, a sub-index is calculated. Each sub-index is determined each day from the maximum levels of the pollutant considered. This is the maximum sub-index that constitutes the final ATMO index characterizing the overall air quality for the day in question.ATMO Index - Sources: Airparif and ATMO FranceYou can find all the Air Quality datasets HEREThe data provider is Airparif >> Index History | AirparifLink Paris.fr >> Air and sound environment - City of Paris; Air quality status in Paris - City of Paris
