Inverse dispersion modelling methods allow the estimation of unknown emission rates from concentration measurements. Improving estimates of methane emissions from sources such as landfill sites is important for quantifying greenhouse gas impacts.</p> <p>The report from this project has now been <a href="https://www.gov.uk/government/publications/quantifying-methane-emissions-using-inverse-dispersion-modelling" title="Access GOV.UK website" target="_blank">published online</a>. It includes: a literature review of different inverse dispersion modelling methods; an assessment of the applicability of inverse dispersion modelling methods to different EA-regulated facilities; a study testing four inverse dispersion modelling methods with measurements from three landfill sites; and recommendations for future use of inverse dispersion modelling.</p> <p>CERC have previously developed and implemented an inverse dispersion modelling approach for improving estimates of <a href="https://doi.org/10.1504/IJEP.2019.104878" title="Access article online" target="_blank">urban emissions</a>. For this project we developed a new &#39;modified Bayesian&#39; inverse modelling technique, due to the short timescale of the plume transect measurements. Measurements at 1 second intervals capture the instantaneous rather than ensemble plume. The concentration <a href="https://cerc.co.uk/environmental-software/assets/data/doc_techspec/P13_01.pdf" title="Download linked document">fluctuations</a> module in <a href="https://www.cerc.co.uk/ADMS" title="Go to ADMS page">ADMS</a> was used to represent the short-term distribution of concentrations, with inverse modelling applied to the peak modelled and measured concentrations only.</p> <p>The <a href="https://www.cerc.co.uk/about-us/assets/news/CERC20231206_inverse_dispersion_large.png" title="View larger image">image</a> shows an example of transect measurements of acetylene (C2H2) tracer gas. The 1 second measured data displays a narrow peak, while standard modelling (&#39;modelled&#39;) predicts a wider plume with a lower peak concentration. The maximum model prediction of 1 second concentrations from the fluctuations module (&#39;modelled fluctuations maximum&#39;, also showing standard deviation error bars) gives good agreement with the peak measurement. Methane measurements from the same transect were used in the inverse modelling study.</p> <br /><br /><img src="http://www.cerc.co.uk/about-us/assets/news/CERC20231206_inverse_dispersion_small.png" width="285" height="230"/> http://www.cerc.co.uk/about-us/news.php?newsitem=405#news405 Wed, 06 Dec 2023 00:00:00 GMT PhD Opportunity to Explore the Pollution-Climate-Health Dilemma http://www.cerc.co.uk/about-us/news.php?newsitem=404#news404 <p><a href="https://cerc.co.uk/" title="Go to CERC homepage">CERC</a> is a partner for a <a href="https://www.envision-dtp.org/2023/the-pollution-climate-health-dilemma-cleaner-air-but-poorer-health-outcomes-under-a-changing-climate/" title="Access Envision website" target="_blank">PhD studentship</a> harnessing data and air pollution modelling to examine the complex interactions between pollution, climate, and health.

Its many features include allowance for the impacts of buildings, complex terrain, coastlines and variations in surface roughness; dry and wet deposition; NOx chemistry schemes; short term releases (puffs); calculation of fluctuations of concentration on short timescales, odours; condensed plume visibility; and allowance for radioactive decay including &gamma;-ray dose.</p> <p>Some of the new features in version 6 of ADMS include</p> <ul><li><strong>Buildings</strong>: enhancements to the modelling of buildings, including the ability to automatically determine a main building. Easier plotting of the effective building and changes to the way the effect of buildings are modelled, particularly for upwind sources.</li> <li><strong>Source apportionment</strong>: the new &#39;output per source&#39; option will write the output contribution from each source to each receptor in a new set of output files. The data in these files can be visualised in the Mapper by colour-coding the sources by what degree each source contributes to the concentration at the selected receptor for a selected met. line.</li> <li><strong>Time-varying emissions</strong>: the ability to specify profiles on a per source per pollutant basis, along with improvements to the entering of time varying emissions factors on screen.</li> <li><strong>New tools</strong>: &#39;Layer statistics&#39; to find and display the minimum, maximum and X, Y location for each numerical field in a layer. ‘Clip layer to polygons’ allows individual features from one layer to be ‘clipped’ to polygon(s) or polyline(s) from a separate layer. Easily create receptor point (.asp) files containing several different sets of 3D gridded output points, in polar, Cartesian or rotated Cartesian form. Open ADMS-Urban and ADMS-Roads model files (.upl files) directly in ADMS.</li> <li><strong>Much more</strong>: Please view all the updates in detail in the <a href="http://www.cerc.co.uk/UserGuides" title="Go to user guides page">What&#39;s New?</a> guide.</li></ul> <p>For further information on this release or any CERC products please <a href="https://www.cerc.co.uk/contact" title="Go to contact us page">email us</a>.</p> <br /><br /><img src="http://www.cerc.co.uk/about-us/assets/news/CERC20230329_ADMS6_1.png" width="390" height="285"/><br /><br /><img src="http://www.cerc.co.uk/about-us/assets/news/CERC20230329_ADMS6_2.png" width="390" height="295"/> http://www.cerc.co.uk/about-us/news.php?newsitem=391#news391 Wed, 29 Mar 2023 00:00:00 GMT New research projects for improved regulatory modelling http://www.cerc.co.uk/about-us/news.php?newsitem=390#news390 <p>Organisations which protect air quality need rapid and robust ways to assess the pollution impacts of industrial activities. The UK <a href="https://www.gov.uk/government/organisations/department-for-environment-food-rural-affairs" title="Access Defra website" target="_blank">Department for Environment, Food & Rural Affairs</a> (Defra) and the <a href="https://www.gov.uk/government/organisations/environment-agency" title="Access Environment Agency website" target="_blank">Environment Agency</a> (EA) commission research to improve regulatory modelling techniques. <a href="https://cerc.co.uk/" title="Go to CERC Homepage">CERC</a> are working on several research projects for both organisations as part of Defra’s Research Development & Evidence Framework Agreement, in collaboration with Air Quality Consultants (<a href="https://www.aqconsultants.co.uk/" title="Access AQC website" target="_blank">AQC</a>).</p> <p>It is important to quantify landfill emissions of methane, a powerful greenhouse gas, but difficult to make accurate and representative emissions measurements. CERC are exploring inverse modelling methods for estimating landfill methane emissions from concentration measurements in two linked projects for the EA. These aim to better understand variations in methane releases and to recommend methods for combining measurements with modelling, to improve ongoing assessments of landfill emissions.</p> <p>CERC and AQC are collaborating on an EA funded study of established and developing air quality assessment methods which use modelling, monitoring and integrated techniques. The aim is to identify aspects of air quality assessment where new research would be valuable. This includes defining preparatory work for new approaches and providing a strategy for future research funding. The project team investigated the opinions of key experts in the field through recent workshops and individual interviews.</p> <p>Carbon capture and storage technologies are being developed to reduce the climate change impacts of combustion processes. Amine chemicals used to remove carbon dioxide from exhaust gases can be released to the atmosphere in small quantities, potentially creating harmful products (nitramines and nitrosamines) through chemical reactions. CERC previously developed <a href="https://www.cerc.co.uk/ADMS" title="Go to ADMS page">ADMS</a> to model amine chemistry. For ADMS 6 this module has been extended to model multiple types of amine and associated products simultaneously. With support from Defra, CERC are investigating sensitivities of the ADMS amine modelling and developing a tool to calculate the chemical properties for a wide range of amines.</p> <p>Air pollution screening methods use simple estimates of impacts to assess whether more detailed modelling is needed. CERC have a leading technical role in an EA funded project to improve screening techniques for small industrial sources. These sources have release heights up to 20 m above ground and are often affected by nearby buildings. CERC are also reviewers in a project for the EA assessing air quality impacts from intermittent generator testing activity.</p> <p>We look forward to sharing project outcomes with the air quality modelling community.</p> <br /><br /><img src="http://www.cerc.co.uk/about-us/assets/news/CERC20230308_projects.jpg" width="450" height="300"/> http://www.cerc.co.uk/about-us/news.php?newsitem=390#news390 Wed, 08 Mar 2023 00:00:00 GMT Recent CERC research publications http://www.cerc.co.uk/about-us/news.php?newsitem=389#news389 <p>Alongside core activities of developing air quality modelling <a href="https://www.cerc.co.uk/ADMS" title="Go to ADMS page">software</a> and providing environmental <a href="https://www.cerc.co.uk/consultancy" title="Go to consultancy page">consultancy</a> services, <a href="https://cerc.co.uk/" title="Go to CERC homepage">CERC</a> take an active role in UK and international scientific <a href="https://www.cerc.co.uk/research" title="Go to research page">research</a> activities. 2022 was a busy year for CERC&#39;s research team, with ten published co-author journal articles.</p> <p>New software development and evaluation was covered in two papers.
