25 Aug 2016ADMLC report on dispersion from agricultural sources published

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).

4 Aug 2016Workshop Reviewing Air Quality Modelling Assessments for Planning

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.

1 Aug 2016airTEXT air quality forecasts for Cambridge

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.

25 Jul 2016Utility to extract ADMS format met data from WRF output (WRFtoMet) available

The WRFtoMet utility is now available as a stand-alone product. This utility extracts ADMS-format meteorological data input files from WRF mesoscale meteorological model output files. It was originally developed for use in the ADMS-Urban Regional Model Link system. As a stand-alone product, it may be useful for creating met data for ADMS or ADMS-Urban modelling in areas where measured meteorological data is unavailable, or for investigating future climate scenarios. More information can be found in the User Guide. Please contact CERC if you would like to purchase this utility or are interested in extracting meteorological data from a different regional model for use with any of the ADMS family of models.

22 Jul 2016New Emissions Factors Toolkit released (version 7.0)

A new version of Defra's Emissions Factors Toolkit (EFT) has been released recently. ADMS-Urban 4.0 and ADMS-Roads 4.0 incorporate the emission factors from version 6 of the EFT. We are currently working to provide the new EFT factors for ADMS-Urban and ADMS-Roads, and aim to make them available in the autumn for model users with a valid support contract.

More information is available about EFT version 7.0 from the Defra website.
