CERC news http://www.cerc.co.uk CERC news en-us 2017 Cambridge Environmental Research Consultants Ltd.Thu, 20 Apr 2017 00:00:00 GMT Optimising local air quality models using sensor data &#45; DMUG 2017 http://www.cerc.co.uk/about-us/news.php?newsitem=243#news243 <p>Amy Stidworthy from CERC recently presented preliminary results from an ongoing project to optimise ADMS-Urban modelling using data from a network of low cost pollution sensors at IAQM&#39;s annual conference for dispersion modellers, <a href="http://iaqm.co.uk/event/dmug-2017/" title="Access IAQM website">DMUG 2017</a>. This work is part of a wider <a href="http://www.cerc.co.uk/about-us/news.php?newsitem=234#news234" title="Go to CERC news">collaboration</a> between CERC, Cambridge University, Cambridge City Council, Cambridgeshire County Council and AQMesh to investigate how modelled and monitored data can be used together to improve urban air quality assessment.</p> <p>Amy&#39;s presentation describes an optimisation scheme, developed at CERC, that minimises the part of dispersion model error which is due to emissions data error by adjusting emission rates on an hourly basis to optimise model performance in comparison with sensor data; the scheme accounts for estimated uncertainty in the sensor and emissions data and complex co-variance between individual source emissions error and between individual sensor error.

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.
