About Chelmsford Air Quality Data

Welcome to Chelmsford Borough Councils' new real-time air quality pages. Launched on December 1st 2007, this site has been designed to provide the public with accurate, precise and up to the minute data from our automatic air quality analysers across the borough.

The data provided within these pages have been designed with functionality in mind. All pollutants that are included on this site can be plotted on a graph and printed out. Visitors to the website can register their email details and data for the selected parameters from each site will be forwarded by email. The system can generate email alerts if a user-selected parameter exceeds a predefined value. This facility may be of benefit for those who are predisposed to suffer the effects of an air pollution episode (e.g. Asthma sufferers).

Please help us improve this service by filling out the feedback form.
