18 Sep 2018CERC sponsor & present at Routes to Clean Air 2018

CERC are once again proud to sponsor the Institute of Air Quality Management's upcoming Routes to Clean Air 2018 conference to be held at the Birmingham Conference and Events Centre on 29-30 October 2018.

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 features an excellent selection of top experts in air quality and related fields including CERC's own Dr Jenny Stocker presenting a talk entitled 'Best Practice Air Quality Modelling Using ADMS'; other relevant topics to be discussed include 'real driving' emissions, population exposure, green infrastructure and wood burning.

Speaker details and information on how to register can be found on the IAQM website here.

CERC will also be exhibiting at the conference, so come and find us to talk about the range of software and consultancy services we provide, or just say hello.

15 Aug 2018ADMS-Urban Regional Model Link results published for London

'Air quality simulations for London using a coupled regional-to-local modelling system' has been published in the open access journal Atmospheric Chemistry and Physics with authors from CERC, the University of Edinburgh and the Centre for Ecology and Hydrology. The paper describes coupled regional-to-local modelling using the ADMS-Urban Regional Model Link system, alongside results from the underlying EMEP4UK (regional) and ADMS-Urban (local) models. Modelled concentrations of NOx, NO2, O3, PM10, PM2.5 and CO are compared against measurements from 2012 at LAQN monitoring sites, with the coupled system shown to perform well at both background and near-road sites. The paper also describes and assesses the effect of adjusting road traffic NOx and PM emissions to reflect real-world conditions, using stand-alone ADMS-Urban modelling.

Contours of concentration for greater London for the modelling year of 2012 from the coupled model are shown in the figure, overlaid with monitoring data shown by round symbols for near-road sites and square symbols for background sites. The contours have been used to assess areas of exceedence for NO2 and PM2.5 annual average air quality standards. This research was part of the CureAir project, funded by NERC.

2 Aug 2018Thurrock joins the airTEXT forecasting service

We are delighted to welcome Thurrock Council to the airTEXT air quality and health forecasting service. Thurrock residents can now sign up for free air quality alerts by SMS text message, email, voicemail, and Twitter. The forecasts are also available on a free phone app for Android.

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.

9 Jul 2018Air quality modelling to support Runnymede's Local Plan

Runnymede Borough Council is preparing a Local Plan to guide development in Runnymede in Surrey, south west of London. The CERC Consultancy team carried out air dispersion modelling using ADMS-Urban to identify the baseline air quality profile across the area and to assess air quality for future scenarios (2030 and 2036), with and without developments associated with the Local Plan in place.

The main source of air pollution in Runnymede is road traffic emissions. The Council has declared two Air Quality Management Areas (AQMAs) due to annual average NO2 concentrations exceeding the Air Quality Objective: along the M25 and in Addlestone town centre.

Modelling for the base year, 2015, showed exceedences of the annual average NO2 Air Quality Objective (AQO) along the M25 and at building façades in Chertsey. In the modelled future scenarios, no exceedences of the AQOs were calculated. This reflects the expected large reduction in NO2 concentrations due to improvements in engine technology, which lead to a fall in traffic exhaust emissions.

The health impact of air quality on health in Runnymede was assessed by calculating the number of attributable deaths and corresponding life-years lost due to concentrations of PM2.5 and NO2. The difference in life years lost with and without the Local Plan in place was very small, reflecting the low concentrations predicted across the Borough.
