Spatial distribution of the monitoring stations in the MRSP. Each marker represents a station that has recorded CO concentration between 1996 and 2013. Black thick line represents the traffic restriction area for light-duty vehicles. SAC and SAP stations are very close and are represented by the same marker. SAP has substituted SAC station (source: OpenStreetMap, 06 Jul 2016).
