ALL CARBON MONOXIDE, SULPHUR DIOXIDE AND HYDROGEN SUPHIDE ANALYSERS HAVE BEEN SWITCHED OFF ON THE 1ST APRIL 2010 TO MAKE SAVINGS AT THE SWANSEA AURN, MORFA GROUNDHOG AND MORRISTON GROUNDHOGS . Suplhur dioxide readings will continue to be made at the St Thomas DOAS monitoring station. Should you wish historical data on the above pollutants then please email pollution@swansea.gov.uk

Please note that should you be browsing this website to obtain meteorological data for an Air Quality Impact Assessment or similar then we have boundary scaling data and climatological datasets available from a 30m meteorological mast at Cwm Level Park, Landore that do not form part of this website. Please contact pollution@swansea.gov.uk should you wish these datasets be forwarded to you.

The Website has been re-launched during the last week of July 2008 following the addition of new features. An easy to understand symbol driven system (to the right) will now take you quickly to the chosen item/feature for that site. Please use the symbol key above these new features to identify the area of interest. In addition links to new data feeds such as the AQ500 Wind Profiler are now live (see below the symbols/station listings)

Swansea has an established programme of automatic and continuous air quality monitoring dating back to 1994. The City & County of Swansea has declared the Hafod district of Swansea as an Air Quality Management Area. Currently, there are 5 air quality stations (two with basic meteorological data), one 30 metre meteorological mast, one street canyon meteorological monitoring station and one AQ500 SODAR (wind profiler)(data coming live soon) providing data to these pages. Additionally, real-time PM₁₀ (dust) data is available from 10 locations in Swansea - mainly around busy junctions.

This website is intended to be an online resource of near real-time air quality data and meteorological data, not only for Swansea residents but also for students and medical health professionals alike.

An index has been created to indicate the number of days Swansea and the individual sites are within the Low/Medium/high and Very High categories - this data is available for the current year as well as previous years.

All passive nitrogen dioxide diffusion tube measurements are now available on line for both historical (indicated as grey) and current measurement sites. Please see the bias correction factor to be applied to the annual mean for the year of interest.

A live traffic cam has been provided to monitor traffic flows within Neath Road, Hafod - please see the Hafod Opsis DOAS station information and look under the link "see monitoring station in action". You will need to install the Axis media plugin to view the live images for which Administrator rights will be needed on Windows XP etc.

The site now has Accessibility Options targeted to comply as closely as possible with the AA standard.
