A new version of Defra's Emissions Factors Toolkit (EFT), version 7.0, was released in July 2016. Details of the updates included in the latest release are summarised on pages 4 and 5 of the EFT User Guide.
ADMS-Urban and ADMS-Roads incorporate the EFT emission factors so that emission rates can be calculated from available traffic and speed data. CERC have compiled a model update that includes the EFT version 7.0 emissions factors, which is available to ADMS-Urban and ADMS-Roads users with current support contracts. Please visit the CERC User Area for a download link.
There will be a talk to summarise this model update at the ADMS-Urban and ADMS-Roads User Group Meeting in Camden, London, on the 10th of November.
This year’s ADMS User Group Meetings are being held at Holiday Inn Camden Lock, London on the 9th and 10th November and are a great opportunity to hear the latest model news and advice from CERC consultants and model developers, to hear talks by model users about their own applications of the software and to network with other model users. Each meeting will start with coffee and registration at 10am and finish at 4pm. A buffet lunch and refreshments are provided. A staffed ‘Helpdesk’ service will be available during all refreshment breaks. ADMS 5, ADMS-Roads, ADMS-Roads Extra, ADMS-Urban, ADMS-Urban Light and ADMS-Airport users with a valid support contract are entitled to one or more delegate places free of charge depending on the type of licence held. Registration will remain open until 31st October 2016 but places are limited, so book your place today!
‘A review of the limitations and uncertainties of modelling pollutant dispersion from non-point sources’ was published earlier this year. This report presents a detailed literature review, including a summary of agricultural and bioaerosol source parameter ranges particularly of interest to those modelling multiple releases from low-level sources in the vicinity of farm sheds. Results from four validation studies are presented, where ADMS and AERMOD have been configured to represent emissions using all available non-point source types. The study recommends that source buoyancy and momentum should be accounted for if these parameters are at least moderately different from ambient conditions; it also includes good practice guidance. This work was funded by the UK Atmospheric Dispersion Modelling Liaison Committee and was co-authored by CERC, Steve Smith (A S Modelling & Data Ltd.) and Akula Venkatram (University of California, CA, US).
CERC are holding a one-day workshop on reviewing air quality modelling assessments, designed for local authorities and anyone involved in reviewing air quality modelling for planning applications. It will consider general principles of air quality modelling with a focus on the ADMS models.
The date of the workshop is Wednesday 8th February 2017, at the Pitt Building, Cambridge. Early-bird registration fee until 16th December: £200; thereafter, registration fee: £250.
To register or for more information, please contact CERC.
Air quality forecasts for Cambridge are now provided on the airTEXT website and phone app.
airTEXT provides three-day forecasts of NO2, PM10, PM2.5 and ozone at street-scale resolution using CERC's ADMS-Urban modelling system. For more information on airTEXT, ADMS-Urban or forecasting services please contact CERC.
