24 Nov 2017High resolution air quality maps of Zagreb

This year, the Croatian environmental consultancy firm EKONERG completed an air quality modelling project for Zagreb City Office in which ADMS-Urban was used to model air pollution levels in Zagreb at street-scale resolution. EKONERG developed a local scale emissions inventory for the project and verified the model predictions at three urban background monitors within the city. The modelled concentrations of NO2 and PM10 were used as input to population exposure calculations.

The background concentration data used in the study were extracted by CERC from the CAMS European-scale air quality ensemble re-analysis product. These data were provided to EKONERG in .bgd file format, for direct inclusion in ADMS-Urban. If you are interested in obtaining European or global modelled background concentration data suitable for use with the ADMS models please contact us.

22 Nov 2017Emissions Factors Toolkit v8 is published by Defra

The Department for Environment, Food & Rural Affairs released a new version of the Emissions Factors Toolkit (EFT). Details of the updates in this new version are given on page 5 of the EFT user guide. The new version of the Excel spreadsheet and the user guide can be downloaded directly from the following links:

ADMS-Airport, ADMS-Urban and ADMS-Roads incorporate the EFT emission datasets so that emission rates can be calculated from available traffic and speed data. CERC are currently working hard to process the new EFT datasets for inclusion with ADMS-Airport, ADMS-Urban and ADMS-Roads v4.1.1, which we expect to release in early 2018 to users with current support. When we have a more exact date we will publish an updated news item on our website. The new model releases are primarily for the EFT, but there will also be a number of interface enhancements to help you with your work. Details will follow, closer to the release date.

We will also be updating EMIT in the new year with EFT 8. This will occur after the ADMS-Airport, ADMS-Urban & ADMS-Roads releases, and once again we will publish more details closer to the release date.

20 Oct 2017CERC presenting high-resolution forecasting for Hong Kong at CMAS 2017

Dr Christina Hood from CERC will present the latest developments to the ADMS-Urban Regional Model Link (RML) system and its use in a high-resolution air quality forecasting system for Hong Kong at the CMAS conference, 23rd-25th October 2017 (extended abstract available here). The integrated regional and local forecasting system has been developed in collaboration with researchers from the Hong Kong University of Science and Technology (HKUST) as part of the PRAISE-HK project. Professor Jimmy Fung from HKUST will talk more about this project in his Plenary presentation on 23rd October. The picture shows contours of high-resolution forecast PM2.5 concentrations for the example domain for 3pm local time on 16th September 2017, using the new ADMS-Urban RML option to interpolate regional model concentrations.

19 Oct 2017Pollution investigation at Wellington Civic Centre

The CERC consultancy team investigated potential sources of high levels of pollution at Wellington Civic Centre offices. In work commissioned by Telford & Wrekin Council, ADMS 5 was used to carry out dispersion modelling of emissions from flues serving the leisure centre adjacent to the offices. CERC determined which sources were responsible for the high pollution levels and supported the design of mitigation measures to tackle the problem.

The modelling required the representation of a complex building arrangement and the calculation of pollution concentrations at both ground-level and elevated locations representing office windows. Modelling of potential mitigation options suggested that a package including changes to flue locations, increased flue heights and renewal of water heater boilers would sufficiently reduce pollution impacts.
