30 Sep 2019Routes to Clean Air 2019

CERC were pleased to attend the Institute of Air Quality Management's annual Routes to Clean Air conference in London on 16th and 17th September.

The Routes to Clean Air conferences provide an opportunity for air quality, public health and transport professionals to share their experiences of improving air quality, particularly in urban areas. This year featured an excellent selection of talks on a range of topics including improving air quality, low cost sensors, transport emissions and health effects.

CERC, a previous sponsor of the event, were there this year as one of the conference exhibitors. Over the two days we were delighted to talk to many of the delegates about our software and consultancy services.

30 Aug 2019CERC supporting environmental research at University College London

This summer, four University College London (UCL) MSc students have been using ADMS-Urban in very different ways for their dissertation projects.

Jingyan Wang and Jinwei Xu are using the advanced street canyon option in ADMS-Urban to model air flow and pollutant dispersion within a street canyon in Nicosia, Cyprus, validating against an earlier field campaign measuring wind flow and pollutant concentrations. Jingyan is evaluating the in-canyon pollutant concentrations, whilst Jinwei is comparing the flow regimes observed in the associated water flume laboratory experiments with the ADMS-Urban in-canyon flow field definition.

Xinning Zhang and Carlos Mestre are using the Temperature and Humidity model, looking at urban heat island impacts on different spatial scales. Xinning has configured ADMS-Urban to calculate local temperature variations within Kampung Baru, an area of traditional timber housing in central Kuala Lumpur, Malaysia. Model predictions of different scenarios are being used to investigate the impact of building morphology and material on the tropical climate (see example modelled temperatures in the image to the right). Carlos is modelling Rotterdam's Urban Heat Island in order to understand the influence of urban geometry. He has analysed the model predictions associated with high-temperature episodes in terms of geometric and aerodynamic properties of the city to allow quantification of the influence of geometry on the spatial variation of temperature within urban areas. Carlos has developed a website which presents his dissertation results.

Jingyan and Jinwei are working with Dr Liora Malki-Epshtein from the Department of Civil, Environmental and Geomatic Engineering. Xinning is working with Dr Kai Wang from the same department — the work being linked to the Newton-Ungku Omar funded project 'Disaster Resilient Cities', which we have previously reported on. Carlos is working with Professor Mike Batty at The Bartlett.

6 Aug 2019Highways England fund feasibility study for modelling elevated roads with ADMS-Urban & ADMS-Roads

We are delighted that Highways England has funded our proposal "Feasibility of tool to assess air quality impacts of elevated roads within the Strategic Road Network (SRN)".

Populations are most exposed to pollution from the SRN in urban areas where the road geometry often includes complex features to improve traffic flow at junctions, such as flyovers and underpasses. There is therefore an urgent need to understand the detailed local air quality impacts of these road features on neighbouring communities.

For this 2-month project, CERC's scientific experts will examine and assess different methodologies for improving the modelling of pollutant dispersion in the vicinity of elevated roads and bridges, to assess the feasibility of developing a new sub-model for ADMS-Roads and ADMS-Urban. Any such model developments would benefit the whole community interested in developing air quality mitigation measures in urban areas, including Highways England and local authority planners.

1 Aug 2019Smart Cities: Hong Kong launch a personalised exposure app

Another significant milestone in the PRAISE-HK project has been reached with the launch in Hong Kong of a real-time personalised exposure app for mobile devices. CERC's technical director, Dr David Carruthers, attended the launch along with representatives from the other partners in this 5-year project to provide Hong Kong citizens with accurate real time and forecast pollution information.

This smart city initiative started in 2017, and CERC have been working closely with the Hong Kong University of Science and Technology to integrate a Linux version of CERC's ADMS-Urban high-resolution air quality model in combination with the CMAQ regional model and WRF meteorological data using our Regional Model Link. The result is a highly detailed street-level pollution map, an example of which can be seen in the app image opposite.

The project's next phase will be to extend the system to include indoor air quality and personalised health recommendations.
