Automatic Networks 

Automatic Networks produce hourly pollutant concentrations, with data being collected from individual sites by modem. The data go back as far as 1972 at some sites.

Information about the automatic monitoring networks in the UK are shown in the navigation on the left.

Each network information page provides information about each network, the pollutants measured, links to view data as well as any related other links.

Most of these automatic networks are shown on the interactive map page.
