Description

Average hourly concentrations from the fixed network of European measurements of the main regulated air pollutants in the Occitanie region: Nitrogen monoxide NO and nitrogen dioxide NO2, suspended particulate matter PM10, suspended particulate matter PM2.5, ozone O3, carbon monoxide CO. All data provided are in μg/m3 (microgram per cubic meter) except CO (mg/m3). The data depth is 72 hours. ATTENTION: The data made available for the last 72 hours as part of our Open Data platform are _raw data_ from our automatic measurement stations. As part of the internal validation procedures, these data may be subject to subsequent corrections. The data is updated every 30 hours, there may be a concern about accessibility to all data at this time. To download the 1-year rolling data in csv format: **Genealogy according to Inspire**: Automatic field measurements. Average concentrations have been calculated in accordance with the Methodological Guide for the Calculation of Air Quality Statistics (LCSQA 2016) from data measured using European or equivalent reference methods (Directives 2008/50/EU and 2004/107/EU).
