Annual ambient air pollutant levels from Great East modelling
Description
Annual levels of nitrogen dioxide NO2 and fine suspended particulate pollutants (PM10, PM2.5) from modelling for the Greater East region for the years 2017 to 2020. The input data used in grid form are concentrations from the modeling chain PREVEST (WRF/CHIMERE models) at 3 km, refined at 1 km according to the GIRAF methodology made available by Air Rhône-Alpes, then corrected by the time measurements of the fixed station network of the Atmo Grand Est network by means of a krigeage of innovations. All data provided are μg/m³ (microgram per cubic metre). Annual statistics refer to nitrogen dioxide as an annual average (µg/m³), fine particulate matter suspended PM10 as an annual average (µg/m³). Annual statistics for PM2.5 suspended fine particulate matter are available for 2020. They are produced annually as part of European reporting.
