11 May 2018Assessment of the FAIRMODE air quality model benchmarking methodology

CERC are co-authors in a recent publication which analyses the strengths and weaknesses of the FAIRMODE benchmarking approach of European-wide, regional and urban scale air quality model applications.

The 'Forum for air quality modelling in Europe' (FAIRMODE) is an EU initiative created in 2007 to bring together air quality modellers and users to promote and support the harmonised use of models across the EU, with emphasis on model application under the European Air Quality Directive.

Dr Jenny Stocker from CERC has attended the FAIRMODE Technical Meetings since 2011, primarily contributing to the Assessment Working Group. A procedure for benchmarking and evaluating EU Air Quality Directive (AQD) modelling applications has been developed within the FAIRMODE framework, leading to free software known as The DELTA Tool. Jenny has co-authored the publication: 'Strengths and weaknesses of the FAIRMODE benchmarking methodology for the evaluation of air quality models', which includes a SWOT analysis of the methodology based on feedback from users of the tool.

30 Apr 2018ADMS-Urban RML to be used to model Delhi air quality

CERC are partners in the 'Process analysis, observations and modelling - Integrated solutions for cleaner air for Delhi' (PROMOTE) project, collaborating with six UK universities and five Indian research institutes. This project will investigate the interactions between meteorological processes such as winter fog events and poor air quality, as well as the relative importance of local and regional pollutant emissions and possible mitigation approaches. It is part of the wider Atmospheric Pollution and Human Health in an Indian Megacity programme, jointly funded by the Natural Environment Research Council (NERC), the Medical Research Council (MRC), the Newton-Bhabha Fund, the Ministry of Earth Sciences (MoES) and the Ministry of Science and Technology Department of Biotechnology.

ADMS-Urban will be used to model street-scale air quality in Delhi during the PROMOTE project. It will be coupled to the regional WRF-Chem and CMAQ models using the ADMS-Urban Regional Model Link (RML) system in order to investigate the interactions of regional and local effects. Preliminary un-coupled ADMS-Urban modelling results were presented at the project science meeting on 24th April 2018. The project brochure gives more information about the full aims of the project and activities of other project partners.

23 Apr 2018airTEXT air quality alerts for Riga

The World Health Organisation warns that air pollution is a major global cause of death and disease, and in sensitive people short-term exposure can lead to reduced lung function, respiratory infections and aggravated asthma. Air pollution levels can vary greatly in just a few hours. Residents of Riga now benefit from a new free service Riga airTEXT, launched on 27 February at Riga City Hall. Riga airTEXT informs the public with free air quality alerts by text message and emails. Air quality forecasts up to three days ahead are available online at www.rigaairtext.lv and in a free phone app. Information is also available from the Riga airTEXT Facebook and Twitter pages.

Now thanks to Riga airTEXT the public can prepare in advance for short-term periods of poor air quality. People with asthma or heart disease can take positive steps, like keeping an asthma inhaler nearby or avoiding strenuous outdoor activity.

A cutting-edge computer system at CERC automatically combines state-of-the-art satellite observations, air quality forecasts for Europe from the EU Copernicus Atmosphere Monitoring Service (CAMS) and ultra-high-resolution air quality forecasts for Riga from the world-leading system ADMS-Urban. ADMS-Urban simulates pollution dispersion and chemical reactions in large urban areas, accounting for thousands of individual sources and the complex air flow produced by buildings and streets. The result is a highly detailed map of street-level air pollution, with more than 100,000 data points.

Riga airTEXT has been developed by UK and Latvian scientists from CERC and ELLE with financial support from the Copernicus Atmosphere Monitoring Service (CAMS). Riga City Council and the Latvian Ministry of Environment are working closely with the Riga airTEXT team to ensure that the service meets the needs of the public.

A short video about Riga airTEXT has been produced by CAMS; to watch this please click here.

For more information on airTEXT, ADMS-Urban or forecasting services please contact CERC.

17 Apr 20182018 ADMS User Group Meetings to be held in Edinburgh, 7-8 November

The 2018 User Group Meetings will be held in Edinburgh on 7th and 8th November.

  • ADMS 5 User Group Meeting: Wednesday 7th November
  • ADMS-Urban and ADMS-Roads User Group Meeting: Thursday 8th 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 a number of free or reduced-rate delegate places 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 open online in the Summer.

10 Apr 2018ADMS-Urban Temperature and Humidity model study of London's Olympic parkland

Dr Jenny Stocker (CERC) co-authored a recently published journal article that explores the sensitivities of the ADMS-Urban Temperature and Humidity model predictions of local urban temperatures to input parameters, using London's Olympic parkland as a case study. In particular, the land use parameters were modified to reflect building materials as well as functional types, causing up to 3°C differences in modelled temperatures; also, the sensitivity of local temperatures to wind speed was assessed. Further work will be carried out to evaluate the input parameters against temperature measurements in Kuala Lumpur under the project Disaster Resilient Cities: Forecasting Local Level Climate Extremes and Physical Hazards for Kuala Lumpur. The paper is freely available online.
