9 Jul 2018Air quality modelling to support Runnymede's Local Plan

Runnymede Borough Council is preparing a Local Plan to guide development in Runnymede in Surrey, south west of London. The CERC Consultancy team carried out air dispersion modelling using ADMS-Urban to identify the baseline air quality profile across the area and to assess air quality for future scenarios (2030 and 2036), with and without developments associated with the Local Plan in place.

The main source of air pollution in Runnymede is road traffic emissions. The Council has declared two Air Quality Management Areas (AQMAs) due to annual average NO2 concentrations exceeding the Air Quality Objective: along the M25 and in Addlestone town centre.

Modelling for the base year, 2015, showed exceedences of the annual average NO2 Air Quality Objective (AQO) along the M25 and at building façades in Chertsey. In the modelled future scenarios, no exceedences of the AQOs were calculated. This reflects the expected large reduction in NO2 concentrations due to improvements in engine technology, which lead to a fall in traffic exhaust emissions.

The health impact of air quality on health in Runnymede was assessed by calculating the number of attributable deaths and corresponding life-years lost due to concentrations of PM2.5 and NO2. The difference in life years lost with and without the Local Plan in place was very small, reflecting the low concentrations predicted across the Borough.

3 Jul 2018Registration is now open for the ADMS User Group Meetings, 7-8 November 2018, Edinburgh

You can register now for the 2018 User Group Meetings, which will be held in Edinburgh on 7th and 8th November.

  • ADMS 5 User Group Meeting: 7th November
  • ADMS-Urban and ADMS-Roads User Group Meeting: 8th November

These meetings will include the usual mix of presentations by CERC staff and software users and are the ideal opportunity to hear the latest news and advice on new model features. Users with a valid support contract are entitled to one or more delegate places free of charge depending on the type of licence held. Please contact CERC if there is a topic you would like to be covered at one of the meetings or if you would like to give a 'user view' presentation. More details will be published later in the year. Registration will remain open until 29th October 2018.

21 Jun 2018‘Hyperlocal’ air mapping in London with smart sensors and Google Street View cars

The Mayor of London, Sadiq Khan, and C40 - a network of cities committed to bold action on climate change - have launched a cutting-edge new project to better understand Londoners' exposure to air pollution around the city. Sensors measuring harmful pollution in tens of thousands of locations will be combined with air quality modelling to produce hyperlocal air quality mapping.

From July, new fixed and mobile sensors will be rolled out across London's streets. 100 fixed sensors will be fitted to lampposts and buildings in the worst affected areas and sensitive locations, and two dedicated Google Street View cars will be driving across the city, mapping air pollution at an unprecedented level of detail. CERC's renowned ADMS-Urban model will be used together with the sensor data to generate hyper-local air quality mapping both for nowcasts and forecasts, and for policy studies.

The project will be run by a team of air quality experts led by the charity Environmental Defense Fund Europe, in partnership with Air Monitors Ltd., Google Earth Outreach, CERC, University of Cambridge, National Physical Laboratory, and the Environmental Defense Fund team in the United States. The press release gives more information on the project.

20 Jun 2018Clean Air Day - 21st June

On Clean Air Day on 21st June organisations across the UK will be taking part in initiatives to highlight the effect that breathing polluted air has on our health and to promote cleaner and healthier ways of getting around. We will be doing our bit on Clean Air Day to make Cambridge air cleaner - 81% of CERC staff will be cycling or walking to work and 19% will be using public transport to get to work. To find out more about Clean Air Day events in your area, go to www.cleanairday.org.uk, or tweet @cleanairdayuk #CleanAirDay to join in the conversation.

11 May 2018Assessment of the FAIRMODE air quality model benchmarking methodology

CERC are co-authors in a recent publication which analyses the strengths and weaknesses of the FAIRMODE benchmarking approach of European-wide, regional and urban scale air quality model applications.

The 'Forum for air quality modelling in Europe' (FAIRMODE) is an EU initiative created in 2007 to bring together air quality modellers and users to promote and support the harmonised use of models across the EU, with emphasis on model application under the European Air Quality Directive.

Dr Jenny Stocker from CERC has attended the FAIRMODE Technical Meetings since 2011, primarily contributing to the Assessment Working Group. A procedure for benchmarking and evaluating EU Air Quality Directive (AQD) modelling applications has been developed within the FAIRMODE framework, leading to free software known as The DELTA Tool. Jenny has co-authored the publication: 'Strengths and weaknesses of the FAIRMODE benchmarking methodology for the evaluation of air quality models', which includes a SWOT analysis of the methodology based on feedback from users of the tool.
