Welcome to the Heathrow Airwatch Homepage

Welcome to the Heathrow Airwatch website, the source for air quality information in the Heathrow area. Here you can get information about where air quality is measured around Heathrow, and see what air quality levels are right now, and over the past week. You may also look at sources of more general information about air quality, including an explanation of the terms used.

For those wanting more detail, additional pages of information are supplied giving a longer history of Heathrow's air quality, and details of additional measurements and reports. This part of the site is aimed primarily at researchers and academics, and as a result the data are quite specialist in nature.

This site has been funded by a joint working partnership consisting of the London Boroughs of Hillingdon and Hounslow, Slough and Spelthorne Borough Councils, BAA Heathrow and British Airways. If you need assistance with any of the information on this site, or local air quality around Heathrow airport, please email us through the 'contact us' page.

Please note that these pages do not attempt to address the issues of greenhouse gas emissions and climate change. We recognise that these are serious issues which have links to health-related air pollutants, but these are beyond the scope of this website. For further information on climate change strategies please contact the relevant project partners.
