ADMS-Roads is designed primarily for networks of roads that may be in combination with industrial sites, for instance small towns or rural road networks. ADMS-Urban can model large urban areas providing output from street-scale to urban-scale.</p> <p>New features in version 4.1 include:</p> <ul><li>project files: allowing background maps, contour plots, layer symbology and more to be saved and reopened with your model input files;</li> <li>quick creation of terrain files from OS terrain 50 and SRTM data formats;</li> <li>road geometry simplification using Douglas-Peucker vertex reduction;</li> <li>file drag-drop and context menus throughout the <a href="http://cerc.co.uk/environmental-software/visualisation-tools.html#mapper" title="Go to ADMS Mapper page">Mapper</a> and interface; and</li> <li>the latest UK emissions factors from EFT 7.0</li></ul> <p>For more information about all the new features please see the relevant <a href="http://www.cerc.co.uk/UserGuides" title="Go to User guides page">What&#8217;s New?</a> guide.</p> <p>Eligible users should log in to the <a href="http://www.cerc.co.uk/UserArea" title="Go to User Area page">User Area</a> in order to download the new versions.</p> <p>For further information please <a href="http://www.cerc.co.uk/contact" title="Go to Contact us page">contact us</a>.</p> <br /><br /><img src="http://www.cerc.co.uk/about-us/assets/news/CERC20170310_ADMS-Urban_Roads4.1.png" width="316" height="285"/> http://www.cerc.co.uk/about-us/news.php?newsitem=239#news239 Fri, 10 Mar 2017 00:00:00 GMT ADMLC report on source term sensitivity in dispersion models http://www.cerc.co.uk/about-us/news.php?newsitem=237#news237 <p><a href="http://www.cerc.co.uk/consultancy" title="Go to Consultancy page">CERC&#39;s consultancy team</a>, with <a href="http://www.gtscience.co.uk/" title="Access GT Science website">GT Science & Software Ltd</a>, has carried out a High Level Review of the Sensitivity of Dispersion Model Predictions to Individual Source Term Parameters. The work was funded by the UK Atmospheric Dispersion Modelling Liaison Committee (<a href="https://www.gov.uk/government/groups/uk-atmospheric-dispersion-modelling-liaison-committee-admlc" title="Access ADMLC website">ADMLC</a>) and the report is freely available <a href="https://admlc.wordpress.com/publications/" title="Download linked document">here</a>.</p> <p>Defining source terms is an essential part of dispersion modelling. A substance can be released into the atmosphere in many different ways, particularly in accidental release situations. It is important to have an understanding of the sensitivity of the model results to each of the source term input parameters.</p> <p>The review discusses the main issues of source term sensitivity, describes a range of commonly-used dispersion models, and presents the results of detailed sensitivity tests. The source terms examined in the review include evaporating pools, pressurised catastrophic failures, jet releases, spray releases, warehouse fires and pool fires.</p> <br /><br /><img src="http://www.cerc.co.uk/about-us/assets/news/CERC20170302_ADLMC.jpg" width="400" height="271"/> http://www.cerc.co.uk/about-us/news.php?newsitem=237#news237 Thu, 02 Mar 2017 00:00:00 GMT CERC workshop: Reviewing Air Quality Modelling Assessments for Planning http://www.cerc.co.uk/about-us/news.php?newsitem=236#news236 <p>In February, <a href="http://www.cerc.co.uk/" title="Go to CERC homepage">CERC</a> held a workshop in Cambridge, UK, attended by over thirty delegates from local authorities and consultancies.</p> <p>The workshop comprised presentations from CERC <a href="http://www.cerc.co.uk/consultancy" title="Go to Consultancy page">consultancy</a> staff and external speakers, as well as breakout discussion sessions.

Comparisons against a reference instrument give very encouraging results, as shown in a paper recently <a href="http://www.ch.cam.ac.uk/files/aw534/RLJ%20AAMG%202016%20c.pdf" title="Download presentation">presented</a> by Professor Rod Jones of the University of Cambridge.</p> <p>The next steps are to compare collected AQMesh data with <a href="http://www.cerc.co.uk/ADMS-Urban" title="Go to ADMS-Urban page">ADMS-Urban</a> modelled data for the same area and then use the real-time AQMesh data to improve CERC&#39;s <a href="http://www.airtext.info/cambridge" title="Go to airTEXT page">air quality forecasts for Cambridge</a>.
