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.
|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.||Traffic, commercial, space heating, regional transport, urban plume downwind of a city.|
