London urban canopy data are now freely available from CERC for use with the Urban Canopy Flow module in ADMS, ADMS-Roads and ADMS-Urban. This module accounts for the effects of urban buildings on local air flow at neighbourhood scales, calculating a spatially varying flow field due to variations in building density and geometry.
The data have been produced for the research project Coupled Urban and Regional processes: Effects on AIR quality (CUREAIR). CUREAIR is a collaboration between CERC, the universities of Edinburgh and Leeds, and the Centre for Ecology & Hydrology. The data are published with a recent paper by CERC and can be re-used without restriction. Download the data here.
More information about the Urban Canopy Flow module is available in the ADMS, ADMS-Roads and ADMS-Urban user guides.
Yesterday at the Architectural Association (AA) in London, Professor Lord Hunt of Chesterton, Director of CERC, chaired a symposium on the state of architecture, public health and urban renaissance in Albania. Erion Veliaj, Mayor of Tirana, spoke at the symposium about the emergence of Albanian society after the fall of Communism in the 1990s, the immense challenges the country faces going forward and the innovative ways his city is tackling these challenges through public engagement, the development of public spaces and art. The meeting was organised by Elsie Owusu OBE and the speakers included leading architects based in London and Albania, public health experts and the economist Dame Frances Cairncross DBE. Amy Stidworthy from CERC gave a presentation about urban air quality and climate. For more information see the AA website.
CERC and Hong Kong Observatory have developed a new system for real-time prediction of wind speed and direction. The system has been successfully applied to Hong Kong Airport, where flights are often disrupted by turbulence downwind of the mountain ridge on Lantau Island. The speed of CERC's FLOWSTAR model enables real-time predictions by integrating real-time wind profiler and radiosonde measurements. The pictures at the right show flight paths, terrain and wind speeds: (left) LIDAR measurements and (right) model predictions. For more information read our paper or contact CERC.
In March, Dr. Jenny Stocker from CERC attended the Air Quality - Science and Application conference in Milan, presenting recent work on regional to roadside modelling and co-chairing a session on 'Development / application / evaluation of air quality and related models' . Jenny's presentation showed analyses derived from ADMS-Urban RML system output, including the influence of local and regional pollutant transport on air quality in London. ADMS-Urban pollutant concentration contours were also shown during Stijn Janssen's presentation on 'FAIRMODE's Composite Mapping Exercise'. Other session topics included measurement and modelling of non-exhaust particulates and urban meteorology. Presentations are now available for download from the conference website.
We are delighted to welcome Colchester Borough Council to the airTEXT air quality and health forecasting service. Colchester residents can now sign up for free air quality alerts by SMS text message, email, voicemail, and Twitter. The forecasts are also available on free phone apps for Android and iPhone.
CERC and the Council have worked together to extend the airTEXT service to the council area. 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.
