The WMS service presents the punctual emissions relating to the production plants and landfills of the Regional Inventory of Atmospheric Emissions (IREA). The data are organized into different levels/layers based on the year of the emissions inventory. The estimates made are calculated based on the INEMAR system (INventario EMissioni ARia) on the basis of the EMEP - CORINAIR methodology and concern sources classified according to the SNAP nomenclature (Selected Nomenclature for Air Pollution). They are classified according to the following parameters: reference year, province and municipality, type of production plant (factory or landfill), company name, address and pollutant emitted. The pollutants exposed by the service are: CH4 (t/year); CO (t/year); CO2 (kt/year); N2O (t/year);NH3 (t/year); NMVOC (t/year); NOX (t/year); PM10 (t/year); PM2.5 (t/year); PTS (t/year); SO2 (t/year).
