Advanced street canyon model derivation and validation published
CERC's article specifying a detailed derivation of the ADMS-Urban and ADMS-Roads advanced street canyon model has been published in the Journal of the Air and Waste Management Association. The advanced street canyon model feature has been included in the ADMS-Urban and ADMS-Roads models since the release of version 4.0 in 2015 and is now widely used by the ADMS modelling community.
The paper also includes the results of validation studies comparing advanced street canyon, non-canyon and basic canyon modelled concentrations with measurements recorded within three individual European street canyons from the TRAPOS study, and with routine air quality monitoring sites across London. The advanced canyon model is shown to have improved performance relative to the basic canyon or non-canyon modelling, particularly in relation to the variation of concentrations with wind direction and prediction of high concentrations.
The picture shows a vertical cross-section of annual average NO2 concentrations at the Marylebone Road monitoring site in London for 2012. The monitored value is shown in a diamond with the corresponding colour.
CERC are currently investigating and developing the advanced street canyon model for a wider range of street canyon configurations, in relation to monitoring data from the UK and Hong Kong. Details of other publications relating to CERC's research are given on the CERC co-author publications page.

FPI Further Enrich its Air Quality Monitoring Products — CAPS NO2 Analyzer
Nitrogen dioxide (NO2) is one subtype of a group of pollutants known as nitrous oxides, or NOx, which are highly reactive gases. Nitrogen dioxide gas can harm human health and environmental quality when it enters the air. Nitrogen dioxide can interact with other chemicals in the air and form acid rain, which in turn can damage ecosystems and human-built monuments, structures, and cultural sites. The nitrate particles that result from nitrous oxides such as NO2 also contribute to haze and decreased visibility....

New Nitrogen Dioxide Sensor for Interference-free Measurements
Low-cost gas-sensitive electrochemical (GSE) nitrogen dioxide (NO2) sensors are used for both indoor and outdoor monitoring. The sensors are stable, long lasting, require very little power and are capable of accurate measurement. These features mean they are often used in compact devices for monitoring outdoor air pollution measurements where NO2 is a criteria pollutant of interest. However, GSE NO2 sensors are susceptible to cross-interference from ozone (O3) when measuring the outdoor air. We have tackled this...
