WMS Service (Web Map Service) Nitrogen Dioxide Assessment (NO2) — Time Limit Value (VLH)

The Web Map Service called Nitrogen Dioxide Assessment (NO2) — Time Limit Value (VLH) allows the visualisation and consultation of the set Information on the evolution of air quality in Spain from 2001 to the last official evaluation generated in response to Directive 2088/50/EC and RD 102/2011 on the improvement of air quality. The mapping included in this service contains the assessment of air quality in Spain for the protection of human health, specifically this service represents compliance with the hourly limit value of nitrogen dioxide (200µg/m³, which cannot be exceeded more than 18 times a year).
