Monitoring site locations

Monitoring sites are classified according to the type of environment in which they are located. This will give a good indication of what pollutants are likely to be found here e.g. Nitrogen Dioxide if there is heavy traffic.

Typical monitoring location types are described in the table below.

Location Description Source Influences
Urban A site within a town or city environment Vehicle, commercial, space heating
Kerbside A site sampling within 1m of the kerb of a busy road. Local traffic
Roadside A site sampling between 1m of the kerbside of a busy road and the back of the pavement. Typically this will be within 5m of the road, but could be up to 15m. Local traffic
Suburban A location type situated in a residential area on the outskirts of a town or city. Traffic, commercial, space heating, regional transport, urban plume downwind of a city.
Urban Background An urban location distanced from sources and therefore broadly representative of city-wide background conditions e.g. urban residential areas Vehicle, commercial, space heating
Urban Centre An urban location representative of typical population exposure in towns or city centres e.g. pedestrian precincts and shopping areas Vehicle, commercial, space heating
Urban Industrial An area where industrial sources make an important contribution to the total pollution burden. Intermediate. 20-30m from the kerb of a busy road. Industrial, motor vehicles.
Rural An open countryside location, in an area of low population density distanced as far as possible from roads, populated and industrial areas. Regional long-range transport, urban plume.
Remote A site in open country, located in an isolated rural area, experiencing regional background pollutant concentrations for much of the time. Regional/hemispheric background.
Intermediate 20-30m from the kerb of a busy road Vehicle, commercial, space heating.
Airport Monitoring within the boundary of an airport perimeter. Aircraft, vehicle, commercial, space heating.
Other Any special source-orientated or location category covering monitoring undertaken in relation to specific emission sources. May be power stations, car parks or tunnels
