Marylebone Road, London - Non-Automatic Data 

The Marylebone Road monitoring site is funded by the London local authorities and the Department for Environment, Food and Rural Affairs (Defra). The site was installed by Environmental Research Group (ERG), King's College London (KCL) in June 1997.

Marylebone Road is a major route in and out of Central London, running north-east to south-west and carrying approximately 90,000 vehicles per day. The tall buildings on either side form a broad street canyon approximately 40 metres across. The monitoring cabin is located one metre from the kerb on the southern side of the road. The site is operated as part of the Automatic London Network and the Automatic Urban and Rural Network (AURN) for the inorganic analysers and as part of the Automatic Hydrocarbon Network (HC) for the gas chromatograph.

The AURN and HC data are available for download from the data selector.

Additional non-AURN parameters such as meteorological measurements, traffic count data, black smoke and metals monitoring data are available for download from this page.
