Average daily concentrations from the fixed network of European measurements of the main pollutants regulated in the air in the Centre-Val de Loire region: * Nitrogen monoxide NO and nitrogen dioxide NO2 * PM10 Suspended Particles * PM2.5 suspended particles * Ozone O3 * Carbon monoxide CO All data provided are in micrograms per cubic metre (μg/m³) except carbon monoxide in milligrams per cubic meter (mg/m³). The data disseminated are raw, they are validated daily and can therefore evolve. A code “Statut_valid” to 0 means that the data is not exploitable. The depth of the data is 1 year. _Genealogy according to Inspire:_ Automatic field measurements.Average concentrations were calculated in accordance with the methodological guide for the calculation of air quality statistics (LCSQA 2016) based on data measured using European or equivalent reference methods (Directives 2008/50/EU and 2004/107/EU).
