CERC, commissioned by Asthma UK and the British Lung Foundation, found that these establishments are in areas with average levels of fine particulate matter (PM2.5) that are above the guideline recommended by the World Health Organisation (WHO) (10&mu;g/m<sup>3</sup> for the annual average).</p> <p>CERC used existing modelled PM2.5 data published by the UK Government as part of their responsibilities under the Environment Act 1995. CERC used predicted annual average PM2.5 data for 2019; these data do not include effects from the COVID-19 &#39;lockdown&#39;. These data have a spatial resolution of 1 km x 1 km, and therefore represent &#39;background&#39; levels of PM2.5. These data give a representative indication of expected PM2.5 levels across the whole of the UK at sufficient resolution to provide good evidence; however they do not capture hyperlocal spatial variations in PM2.5 levels caused by road traffic.</p> <p>The research covers England, Scotland and Wales. Postcodes for schools were extracted from the Scottish government school statistics and the English and Welsh government register of schools and colleges. In total, 31,979 schools and colleges were included.</p> <p>Asthma UK and the British Lung Foundation want the government to commit to a stronger and safer new legal limit for PM2.5 in the Environment Bill in line with WHO guidelines.</p> http://www.cerc.co.uk/about-us/news.php?newsitem=339#news339 Fri, 11 Sep 2020 00:00:00 GMT EFT 10.1 update for ADMS-Roads, ADMS-Urban and ADMS-Airport http://www.cerc.co.uk/about-us/news.php?newsitem=338#news338 <p>The UK Department for Environment, Food & Rural Affairs and the Devolved Administrations have released version 10.1 of the <a href="https://laqm.defra.gov.uk/review-and-assessment/tools/emissions-factors-toolkit.html" title="Access Defra's website" target="_blank">Emissions Factors Toolkit</a> (EFT).

Research undertaken by CERC&#39;s CASE student, Michael Biggart at the <a href="https://www.ed.ac.uk/geosciences" title="Access University of Edinburgh website" target="_blank">University of Edinburgh</a>, has been published in the paper &#39;<a href="https://search.proquest.com/openview/ca477e1acf257ae4420722f79c4852f6/1?pq-origsite=gscholar&cbl=105744" title="Access article online" target="_blank">Street-scale air quality modelling for Beijing during a winter 2016 measurement campaign</a>&#39;. One challenge of this work was to develop an emissions inventory for this megacity; model predictions have been compared to air quality measurements recorded during the NERC-funded project: &#39;An Integrated Study of AIR Pollution PROcesses in Beijing (<a href="https://gtr.ukri.org/projects?ref=NE%2FN007093%2F1" title="Access UKRI website" target="_blank">AIRPRO</a>)&#39;. The figures show period-average measurements overlaid on modelled pollutant contours (NO2, top and ozone, bottom) for the region within Beijing&#39;s fifth ring road.</p> <p>Results from one of the first applications of CERC&#39;s emissions-optimisation scheme have been published (<a href="https://www.inderscienceonline.com/doi/abs/10.1504/IJEP.2019.104878" title="Access article online" target="_blank">Carruthers et al., 2019</a>). This method applies a Bayesian inversion technique to high resolution ADMS-Urban modelled concentrations in order to modify pollutant emission rates based on sensor data. The scheme was tested in Cambridge using monitored data from four <a href="https://www.cambridge.gov.uk/air-pollution-levels-and-monitoring-them" title="Access Cambridge City Council website" target="_blank">Cambridge City Council</a> air quality reference monitors and 20 <a href="https://www.aqmesh.com/product/aqmesh/" title="Access AQMesh website" target="_blank">AQMesh</a> sensor pods provided by the <a href="https://www.ch.cam.ac.uk/" title="Access University of Cambridge website" target="_blank">University of Cambridge</a>. The optimisation scheme improved model accuracy at the reference sites by reducing estimated road emissions by 6.5% on average and changed the diurnal profile of emissions. This same scheme has been used to estimate emissions reductions resulting from COVID-19 restrictions in London (see 9<sup>th</sup> April <a href="http://www.cerc.co.uk/about-us/news.php#news328" title="Go to CERC News page">News item</a>).</p> <p>An article describing the &#39;Personalised Real-Time Air Quality Informatics System for Exposure &ndash; Hong Kong&#39; (<a href="http://praise.ust.hk/" title="Access PRAISE-HK website" target="_blank">PRAISE-HK</a>) system has been published (<a href="https://www.sciencedirect.com/science/article/abs/pii/S2210670719335279?via%3Dihub" title="Access article online" target="_blank">Che et al., 2020</a>).

The 2-year project is developing a coupled air quality modelling system spanning national to urban street scales and accounting for physical and chemical processes at all relevant temporal and spatial scales. The system will be flexible, linking established regional chemical transport models including CMAQ, CAMx, EMEP and WRF-Chem and a new street-scale model ADMS-Local derived from the widely used model <a href="https://cerc.co.uk/ADMSUrban" title="Go to ADMS-Urban model page">ADMS-Urban</a>. A verification module will enable validation of model predictions. The project is funded under the Clean Air Programme of the Strategic Priorities Fund (SPF). The coupled system and ADMS-Local will be available to the UK research community via the SPF Clean Air Framework platform and will have an open structure facilitating system development and modification. The project team brings together CERC&#39;s experts in software development and application of local dispersion models (ADMS), and regional model experts from the universities of Birmingham, Edinburgh, Hertfordshire and Lancaster. The team are working closely with the Met Office who led the call for this project, and will continue to liaise with stakeholders as the project progresses.</p><br /><br /><img src="http://www.cerc.co.uk/about-us/assets/news/CERC20200414_MAQS-Health.png" width="385" height="125"/> http://www.cerc.co.uk/about-us/news.php?newsitem=329#news329 Tue, 14 Apr 2020 00:00:00 GMT Assessing the drop in London road traffic emissions during COVID-19 restrictions http://www.cerc.co.uk/about-us/news.php?newsitem=328#news328 <p>The restrictions imposed by the UK Government to limit the spread of COVID-19 have led to unprecedented reductions in the volume of road traffic; the latest <a href="https://www.gov.uk/government/publications/slides-and-datasets-to-accompany-coronavirus-press-conference-6-april-2020" title="Access UK Gov website" target="_blank">Government figures</a> suggest that vehicle use has dropped to 40% of normal levels. Discerning the impact of this on air quality in our towns and cities is difficult however, because air quality is heavily dependent on the weather. In typical windy UK conditions, poor air is rapidly mixed with cleaner air from above, so only those nearest to the busiest roads experience poor air quality. However, when the wind is light, as it was during the fine sunny weather that immediately followed the imposition of COVID-19 restrictions on 23<sup>rd</sup> March, traffic pollution emitted into stagnant air builds up, leading to more widespread poor air quality. So how can we tease out the impact of the known recent reduction in vehicle use from measured air quality data?</p> <p> Scientists at CERC have analysed recent measured air quality data from across London using a mathematical technique (<a href="http://www.cerc.co.uk/environmental-software/CERC-coauthor-publications.html" title="Go to CERC coauthor publications page">Carruthers et al., 2019</a>) that combines measured air pollution concentration data with CERC&#39;s <a href="https://cerc.co.uk/ADMSUrban" title="Go to ADMS-Urban model page">ADMS-Urban</a> air quality model to derive an estimate of the underlying road traffic emissions that caused the measured concentrations. The figure shows how measured concentrations and derived emissions have changed since the 16<sup>th</sup> March, when the Government first issued social distancing advice (a high-resolution figure is <a href="http://www.cerc.co.uk/about-us/assets/news/CERC20200409_London_COVID19_large.png" title="View image" target="_blank">here</a>). The derived emissions first show a marked drop over the weekend of 21<sup>st</sup>/22<sup>nd</sup> March, which coincides with the announcement on the evening of Friday 20<sup>th</sup> March that bars and restaurants should close. Monday 23<sup>rd</sup> March saw a <a href="https://www.itv.com/news/london/2020-03-23/tube-platforms-extremely-busy-despite-mayor-s-warning-only-travel-if-you-absolutely-must/" title="Access ITV website" target="_blank">widely-reported</a> rush hour in London; this can be seen in both the measured concentrations and the derived emissions. The impact of the restrictions announced in the evening of 23<sup>rd</sup> March can be seen in the derived emissions in the following days, even though measured concentrations continued to rise through Wednesday, due to the sunny and still weather conditions. The lowest derived emissions are seen on the weekend of 28<sup>th</sup>/29<sup>th</sup> March, averaging 24% of pre-restriction levels. Weekday derived emissions of consistently around 40% of pre-restriction levels contrasts with a second peak in measured concentrations on 1<sup>st</sup> April, again due to still weather conditions. From today, CERC&#39;s air quality forecasting services for <a href="http://www.airtext.info/" title="Access airTEXT website" target="_blank">London and the South-East</a> have been adjusted to include this temporary reduction in road traffic.</p> <p>By combining air quality monitoring with dispersion modelling, CERC scientists have been able to show that as well as limiting the spread of COVID-19, the Government restrictions are leading to a reduction in traffic emissions in London. In more normal times in future, this type of analysis can help uncover the true impact of emissions-reduction strategies on local air quality.</p><br /><br /><img src="http://www.cerc.co.uk/about-us/assets/news/CERC20200409_London_COVID19_small.png" width="479" height="479"/> http://www.cerc.co.uk/about-us/news.php?newsitem=328#news328 Thu, 09 Apr 2020 00:00:00 GMT Major new release of ADMS-Urban, ADMS-Roads & ADMS-Airport http://www.cerc.co.uk/about-us/news.php?newsitem=327#news327 <p>Version 5 is a major update of <a href="http://www.cerc.co.uk/Urban" title="Go to ADMS-Urban page">ADMS-Urban</a>, <a href="http://www.cerc.co.uk/Roads" title="Go to ADMS-Roads page">ADMS-Roads</a> and <a href="http://www.cerc.co.uk/airport" title="Go to ADMS-Airport page">ADMS-Airport</a> with many powerful new features to aid modelling, data processing and visualisation.</p> <p>ADMS-Urban, ADMS-Roads and ADMS-Airport are comprehensive tools for investigating air pollution taking account of complex urban morphology including street canyons and road tunnels.

Ideal when using <a href="http://www.cerc.co.uk/RunManager" title="Go to Run Manager page">Run Manager</a></li> <li><strong>Source exclusion</strong>: option to exclude low-emitting sources from the model run, which can help to reduce run times.</li> <li><strong>Source apportionment</strong>: output the contribution of each source to each receptor, along with visualisation in the <a href="http://www.cerc.co.uk/environmental-software/visualisation-tools.html#mapper" title="Go to visualisation tools page">Mapper</a>.</li> <li><strong>EFT 9.0</strong>: includes the latest UK emission factors, which include the effects of road gradients on emissions from heavy goods vehicles.</li> <li><strong>Time-varying emissions</strong>: Now allows for different factors for specific source-pollutant combinations.</li> <li>Plus many enhanced usability functions throughout the Mapper and interface.</li></ul> <p>All the new features are described in detail in the <a href="http://www.cerc.co.uk/UserGuides" title="Go to User Guides page">What&#39;s New?</a> guides.</p> <p>Users with support will get this version within the next few working days.</p> <p>For further information on this release or any CERC products please <a href="http://www.cerc.co.uk/contact" title="Go to Contact us page">email us</a>.</p> http://www.cerc.co.uk/about-us/news.php?newsitem=327#news327 Fri, 03 Apr 2020 00:00:00 GMT Communications with CERC during the COVID-19 pandemic http://www.cerc.co.uk/about-us/news.php?newsitem=326#news326 <p>During these extraordinary times of reduced social interaction and home working, CERC will be making sure we continue to interact with and support our model users and clients.</p> <p>We will be handling all email helpdesk and enquiries as usual, but we are temporarily replacing telephone support, so please email for everything!</p> <p>Please see our <a href="https://cerc.co.uk/about-us/contact-us.html" title="Go to Contact us page">contact</a> page for details.</p> <p>Similarly, please use email for communications about ongoing projects.</p> <p>We will update our <a href="https://cerc.co.uk" title="Go to CERC homepage">website</a> if there are any changes to this.</p> http://www.cerc.co.uk/about-us/news.php?newsitem=326#news326 Wed, 18 Mar 2020 00:00:00 GMT
