ADMS-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.
