The <a href="http://www.cerc.co.uk/consultancy" title="Go to Consultancy page">CERC Consultancy</a> team carried out air dispersion modelling using <a href="http://www.cerc.co.uk/Urban" title="Go to ADMS-Urban page">ADMS-Urban</a> 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.</p> <p>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 NO<sub>2</sub> concentrations exceeding the Air Quality Objective: along the M25 and in Addlestone town centre.</p> <p>Modelling for the base year, 2015, showed exceedences of the annual average NO<sub>2</sub> Air Quality Objective (AQO) along the M25 and at building fa&ccedil;ades in Chertsey. In the modelled future scenarios, no exceedences of the AQOs were calculated. This reflects the expected large reduction in NO<sub>2</sub> concentrations due to improvements in engine technology, which lead to a fall in traffic exhaust emissions.</p> <p>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 PM<sub>2.5</sub> and NO<sub>2</sub>. 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.</p> <br /><br /><img src="http://www.cerc.co.uk/about-us/assets/news/CERC20180709_Runnymede1.jpg" width="332" height="349"/><br /><br /><img src="http://www.cerc.co.uk/about-us/assets/news/CERC20180709_Runnymede2.jpg" width="486" height="344"/> http://www.cerc.co.uk/about-us/news.php?newsitem=281#news281 Mon, 09 Jul 2018 00:00:00 GMT Registration is now open for the ADMS User Group Meetings, 7-8 November 2018, Edinburgh http://www.cerc.co.uk/about-us/news.php?newsitem=280#news280 <p>You can <a href="http://www.cerc.co.uk/software-support/user-group-meetings.php" title="Go to UGM page">register now</a> for the 2018 User Group Meetings, which will be held in Edinburgh on 7<sup>th</sup> and 8<sup>th</sup> November.</p> <ul><li>ADMS 5 User Group Meeting: 7<sup>th</sup> November</li> <li>ADMS-Urban and ADMS-Roads User Group Meeting: 8<sup>th</sup> November</li></ul> <p>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.

Sensors measuring harmful pollution in tens of thousands of locations will be combined with air quality modelling to produce hyperlocal air quality mapping.</p> <p>From July, new fixed and mobile sensors will be rolled out across London&apos;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&apos;s renowned <a href="http://www.cerc.co.uk/ADMSUrban" target="_blank" >ADMS-Urban model</a> will be used together with the sensor data to generate hyper-local air quality mapping both for nowcasts and forecasts, and for policy studies.</p> <p>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.

They are using <a href="http://www.cerc.co.uk" title="Go to CERC homepage">CERC</a>&#39;s world-leading <a href="http://www.cerc.co.uk/Urban" title="Go to ADMS-Urban model page">ADMS-Urban</a> model, which includes street-scale to city-wide scale modelling, advanced treatments of airflow, turbulence and dispersion within the city taking account of the effect of buildings and street canyons, chemical reactions and the mixing of pollution due to traffic.</p> <p>As described in <a href="http://www.parliament.scot/parliamentarybusiness/105527.aspx" title="Access linked document" target="_blank">evidence</a> to the Scottish Parliament air quality committee, the ADMS-Urban output (<a href="http://cerc.co.uk/about-us/assets/news/CERC20180302_Glasgow_LEZ1large.jpg" title="View image">first image</a>) are predicted annual-mean concentrations of NO<sub>2</sub> at points around the city, with the colour indicating whether they are above (red) or below (green) the annual-mean threshold of 40&#956;g/m<sup>3</sup>.</p> <p>The <a href="http://cerc.co.uk/about-us/assets/news/CERC20180302_Glasgow_LEZ2large.jpg" title="View image">second image</a> shows good agreement between modelled air-quality concentrations for 6 sites compared with the monitored values at these sites in 2015 using the &#39;congested speed&#39; scenario. In particular the large roadside increment is well represented by the model. No model adjustment factors have been used in this project.</p> <p>Two LEZ scenarios have been investigated with ADMS-Urban and CERC&#39;s <a href="http://cerc.co.uk/EMIT" title="Go to EMIT model page">EMIT</a> emissions inventory tool: (1) assuming all buses are at EURO VI, and (2) additionally assuming diesel cars and LGVs are at Euro 6 and petrol cars and LGVs are at EURO 4 or newer. At a monitor location within the LEZ, the greatest improvement in air quality was predicted by cleaning the bus fleet, with a small additional improvement by targeting cars and LGVs. The modelling work is continuing efficiently and the Glasgow LEZ is <a href="https://news.gov.scot/news/first-low-emission-zone-for-glasgow" title="Access Scottish Government website" target="_blank">expected</a> to be in place by the end of 2018.</p><br /><br /><img src="http://www.cerc.co.uk/about-us/assets/news/CERC20180302_Glasgow_LEZ1small.jpg" width="423" height="400"/><br /><br /><img src="http://www.cerc.co.uk/about-us/assets/news/CERC20180302_Glasgow_LEZ2small.jpg" width="420" height="105"/> http://www.cerc.co.uk/about-us/news.php?newsitem=270#news270 Tue, 13 Mar 2018 00:00:00 GMT
