Automatic London Network
Introduction
The Automatic London Network is a subset of sites in the AURN which also form part of the wider London Air Quality Network (LAQN).
What is measured?
The table of parameters lists everything measured since the AURN network started, and is not necessarily what the network is measuring at this current time.
| Parameters Measured | Monitoring sites and data |

How is the network run?
Defra's Automatic London Network is run by Bureau Veritas with Quality Assurance and Quality Control (QA/QC) activities contracted to the National Physical Laboratory. Pollutant concentrations at each site are measured and collected automatically every hour for public information. The results are then made available for further research and analysis from the Data Archive section of UK-AIR.
