Annual modelling of key pollutants in the Southern region

Annual levels of nitrogen dioxide pollutants NO2, PM10 suspended particulate matter, ozone O3 and the Air Synthetic Index (ISA) in ambient air, derived from modelling of the South region by year over the last 5 years. All data provided are μg/m³ (microgram per cubic metre). Statistics according to the regulations in force for each pollutant: * PM10: 36th highest daily average. Unit: microgram per cubic meter (µg/m³). * PM10: annual average. Unit: microgram per cubic meter (µg/m³). * PM2.5: annual average. Unit: microgram per cubic meter (µg/m³). * NO2: annual average. Unit: microgram per cubic meter (µg/m³). * O3: 26th daily maximum of the highest 8h average. Unit: microgram per cubic meter (µg/m³). * ISA: non-regulatory index combining annual concentrations of NO2, PM10 and O3 standardised by their respective WHO guidelines. Values without unit, usual variations between 0 and 100. Data created with a local atmospheric dispersion model (ADMS Urban). Use of the Southern Emission Inventory. Statistics comparable to limit values for health protection: Decrees No 98-360, 2002-213, 2003-1085, 2007-1479, 2008-1152, 2010-1250 and Directive 2008/50/EC. Modeling carried out in accordance with the recommendations of the Central Air Quality Monitoring Laboratory (LCSQA). The resolution is 25 m for all layers, except those for ozone that are 1 km away.
