CERC news http://www.cerc.co.uk CERC news en-us 2020 Cambridge Environmental Research Consultants Ltd.Fri, 03 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. 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. ADMS-Airport has the features of ADMS-Urban, and can also incorporate all relevant emission sources at airports by using algorithms designed specifically to model dispersion from aircraft engines.</p> <p>Some of the new features in version 5 include</p> <ul><li><strong>Run splitting</strong>: option to automatically break a large modelling region into smaller spatial regions, which can be distributed across your available processors to significantly reduce turnaround times. 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 Investigating emission limits for the Norwegian Environment Agency http://www.cerc.co.uk/about-us/news.php?newsitem=325#news325 <p>The <a href="https://tema.miljodirektoratet.no/en/" title="Access Norwegian Environment Agency website" target="_blank">Norwegian Environment Agency</a> has commissioned <a href="http://cerc.co.uk/" title="Go to CERC homepage">CERC</a> to study how air concentration benchmarks for specific metals and polycyclic aromatic hydrocarbons (PAHs) correspond to annual emissions to air from a particular source.</p> <p>In Norway, the major industrial sources of these emissions are non-ferrous metal industries such as aluminium and manganese production. Other contributors include graphite producers, inorganic chemical manufacturers and oil and gas refineries.</p> <p>The key question in the study is how much can be emitted for a given set of emission parameters before the concentration benchmarks are reached? The answer will be determined through modelling using CERC&#39;s industrial dispersion model <a href="https://www.cerc.co.uk/environmental-software/ADMS-model.html" title="Go to ADMS 5 page">ADMS 5</a>.</p> <p>The Norwegian Environment Agency will use the results for screening, to decide whether detailed dispersion modelling is required for a specific facility.</p><br /><br /><img src="http://www.cerc.co.uk/about-us/assets/news/CERC20200205_Norwegian_refinery.jpg" width="370" height="215"/> http://www.cerc.co.uk/about-us/news.php?newsitem=325#news325 Wed, 05 Feb 2020 00:00:00 GMT Breathe London wins Smart 50 Award http://www.cerc.co.uk/about-us/news.php?newsitem=324#news324 <p>The <a href="https://www.breathelondon.org/" title="Access Breathe London website" target="_blank">Breathe London project</a> has won a <a href="https://spring.smartcitiesconnect.org/Smart50Awards/" title="Access Smart 50 Awards website" target="_blank">Smart 50 Award</a> from Smart Cities Connect, in the Digital Transformation category. These annual awards recognize global smart cities projects, honouring the most innovative and influential work.</p> <p>In the project Google Earth Outreach have equipped two of their iconic Street View cars with air quality sensors. These have taken pollution readings approximately every 30 metres whilst they travelled through London's streets over one year.

For example, wipes are no longer used anywhere in the office. All liquid soap bottles are replenished using a supply chain entirely based on refills. Everyday plastic waste is encouraged to be recycled in bins placed strategically throughout the office. All purchased milk is delivered in reusable glass bottles. Only dishwasher tablets wrapped in fully biodegradable/compostable wraps are consumed. Environmentally friendly cleaning agents are used and then restocked on a refill basis. Paper bags are provided for sanitary use.</p> <p>Concern for the environment and promoting a broader sustainability agenda are integral to our professional activities and the management of our organisation. For example, our staff use green transport options whenever possible, with about 80% cycling or walking to work, and most others using public transport. CERC has a Sustainability Statement, which can be issued upon request.</p> http://www.cerc.co.uk/about-us/news.php?newsitem=323#news323 Thu, 19 Dec 2019 00:00:00 GMT Software development vacancy http://www.cerc.co.uk/about-us/news.php?newsitem=322#news322 <p>We are seeking an enthusiastic software developer to join the <a href="http://www.cerc.co.uk/" title="Go to CERC homepage">CERC</a> scientific development team.
