General Issues
The Webcam located at the 30m Cwm Level Park Meteorological Monitoring station has been stolen off the mast. Unfortunately, there are no plans to replace the Axis Webcam due to financial restrictions. Some meteorological data is missing from 13th and 14th June as the cut power cables to the webcam tripped the power to the whole meteorological mast. Similarily, some air quality data (NOx and Ozone) are missing during the same timescale. The Hafod DOAS wecam is operating normally. We apologise for the inconvenience.

Following on from the theft of the webcam (see above) at our Cwm Level Park site, the culprits have returned at 20:01 on Friday 23rd August 2013. This time they have stolen the central data logger on site and have cut numerous cables as well as vandalising other sensors with the destruction of the locking mechanisms to the site enclosure. The culprits have also attempted to gain access to the other site enclosure that houses the real time NOx and Ozone analysers. However, whilst extensive damage has been caused to the enclosure they did not manage to gain access.

Communications with the NOx and Ozone analysers has been lost as the ADSL telephone line has been cut within the site enclosure. Attempts will be made to regain communications but for the foreseeable future, there will be no meteorological data reported from the site. We regret any inconvenience this may cause. In the meantime our Swansea Bay meteorological station is providing data to this website.

The SODAR (currently located in Glais within the upper Swansea Valley) is offline due to a break in the power supply. The unit is likely to be offline for some time whilst a new supply is installed.

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 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

The Morfa Groundhog site was decomissioned during May 2010. Historic data is available.

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. 

A new menu to display the particulate PM10 monitoring being undertaken around Cwmrhydyceirw Quarry is now live. Data will be displayed during both the preparatory and operational phases of this landfill site.

A new meteorological monitoring station (Swansea Bay) has been established within 20m of the Swansea Bay foreshore at Blackpill during May 2010 to provide high quality meteorological data to assist with a major EU funded study into the bathing water quality within Swansea Bay.

An easy to understand symbol driven system (to the right) will 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 Swansea Air Quality Management Area 2010 that encompasses the areas of Hafod, Sketty and Fforestfach during August 2010. Currently, there are 4 air quality stations (two with basic meteorological data), one 30 metre meteorological mast, one 9m meteorological mast on Swansea bay foreshore at Blackpill, one street canyon meteorological monitoring station and one AQ500 SODAR (wind profiler) 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.
