25 Aug 2020Summer 2020 editions of ADMS Model Newsletters now available

Catch up on ADMS model news in the Summer 2020 editions of ADMS 5 & ADMS-Screen News and ADMS-Urban & ADMS-Roads News which are now available. The newsletters are published approximately twice a year and include the latest news about the ADMS models, the annual User Group Meetings, CERC activities, training courses and recently published papers as well as a page of useful modelling tips. Previous editions of the newsletters are available here.


19 Aug 2020Source apportionment of pollution on Breathe London map

The Breathe London map now shows how different polluting activities contribute to the concentration of nitrogen oxides at Breathe London sensor locations across the city. Just search for or click on any sensor.

CERC modelled pollution sources across London for 2019 using our ADMS-Urban software to quantify the contributions from twenty source categories at different points. We integrated the modelling output onto the Breathe London map developed by CERC. This is the first time hyperlocal modelled source apportionment data has been displayed alongside current pollution measurements on an interactive public map. With a better understanding of which activities are causing pollution, leaders and communities can develop targeted solutions that clean the air and protect public health.

Starting today the Breathe London map also shows air quality alerts from CERC's airTEXT forecasting service for London and the South East.

Breathe London is a consortium led by the Environmental Defense Fund, including CERC, Air Monitors, University of Cambridge, National Physical Laboratory and Google Earth Outreach.

14 Aug 2020Changes to the CERC User Area

We have moved our User Area downloads to a new platform hosted by Citrix. We think the new system will make it much easier for you to find what you are looking for. You will still be able to use links on our website, but once logged in you can browse everything there is to download in a simple folder structure.

If you are currently registered, with a login and password, you will soon get an email from us inviting you to sign up to the new User Area downloads. Just click the link, which will take you to the 'Welcome' screen containing your details where you can enter a new password to gain access to the latest software releases, technical guidance, modelling support documents and more.

For any of our users who are not yet taking advantage of the User Area downloads, you can sign up via the online form. The User Area is for all customers with current support for one of more of our products.


31 Jul 2020London road traffic NOx emissions still below 50% of pre-COVID-19 levels

CERC continues to run its inverse modelling system (details in our April News item) to determine NOx emissions in London as easing of the lockdown progresses. The latest model calculations up to July 17 show that whilst there has recently been some increase in emissions, they typically remain below 50% of the pre-COVID values. Consistent with this, London road traffic NOx emissions for our airTEXT air quality forecasting using our ADMS-Urban model are currently set at 40% of 'normal'. Resultant forecasted NO2 concentrations are low compared with usual levels but on average are showing a slight overestimate compared with measured values.

29 Jun 20202020 ADMS User Group Meetings to be held online, 18-19 November

We are pleased to announce that the 2020 ADMS User Group Meetings will be held on 18th and 19th of November. This year they will be held online due to the ongoing uncertainty around the COVID-19 situation. The meetings will include the usual mix of presentations by CERC staff and software users and are the ideal opportunity to hear the latest news and advice on new model features. More details will be published later this summer.

You can also follow CERC news on Facebook, Twitter, LinkedIn and by RSS.
