6 Jul 2017Registration is now open for the ADMS User Group Meetings, 1-2 November 2017, Birmingham

You can register now for the 2017 User Group Meetings, which will be held in Birmingham on 1st and 2nd November.

  • ADMS 5 User Group Meeting: 1st November
  • ADMS-Urban and ADMS-Roads User Group Meeting: 2nd November

These 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. Users with a valid support contract are entitled to one or more delegate places free of charge depending on the type of licence held. Please contact CERC if there is a topic you would like to be covered at one of the meetings or if you would like to give a 'user view' presentation. More details will be published later in the year. Registration will remain open until 23rd October 2017.

26 Jun 2017China-UK Urban Air Quality Management Workshop in Beijing

Air quality is one of the most critical environmental issues in China. CERC, in partnership with the School of Environment, Beijing Normal University, held a China-UK Urban Air Quality Management Workshop in Beijing on 13 June 2017. There were 20 speakers at the event, with over 90 participants. The topics covered air quality forecasting, urban air quality management, urban traffic pollution, air quality and climate change, air quality modelling at regional and local scales, source apportionment shipping emissions etc. Speakers also shared the Swiss air quality management experience, as well as Asia experience. CERC Director Dr David Carruthers presented CERC's regional and local scales nested modelling approaches. Local fine scale models such as ADMS-Urban are particularly important when pollution mitigation scenarios are tested.

15 May 2017Clean Air Zones

On 5 May the UK government published the principles for setting up new Clean Air Zones in England, which can include charges for older vehicles which do not meet emission standards such as Euro 6. Local authorities who propose Clean Air Zones must consider the sources of vehicle pollution in their area to ensure the zone design is appropriate to meet the air quality challenge.

CERC's ADMS-Urban and EMIT software are invaluable aids in these assessments, allowing:

  • Source apportionment of emissions and concentrations, for instance to determine the relative contributions from diesel cars below Euro 6 standard. Map 1 shows the proportion of total NOx concentration due to particular vehicle types at specific locations.
  • Assessment of the impact of measures, including changes in emissions and concentrations due to changes in road traffic flows and fleet composition. Map 2 shows the changes in emissions predicted from the implementation of a mitigation measure.

The two maps are taken from recent studies by CERC's consultancy team, who have extensive experience in assisting local authorities to assess air quality measures on challenging timescales. The ADMS-Urban and EMIT software tools are available for use in assessments by local authorities or consultants. For more information please contact CERC, and one of our technical consultants will be delighted to discuss your requirements.

20 Apr 2017Optimising local air quality models using sensor data - DMUG 2017

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's annual conference for dispersion modellers, DMUG 2017. This work is part of a wider collaboration 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.

Amy'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.
