WMS (Web Map Service) Stations Nitrogen Dioxide (NO2) – Annual Limit Value (VLA)

The Web Map Service called Nitrogen Dioxide Stations (NO2) – Annual Limit Value (VLA) allows the visualisation and consultation of the cartography containing the fixed air quality stations that have been used to carry out the assessment in accordance with Directive 2088/50/EC and RD 102/2011 on the improvement of air quality. The Annual Limit Value for Nitrogen Dioxide is 40µg/m³.
