A comprehensive experimental databank for the verification of urban car emission dispersion models
A summary presentation is made of representative samples from a comprehensive experimental databank on car exhaust dispersion in urban street canyons. Physical modelling, under neutral stratification conditions, was used to provide visualisation, pollutant concentration and velocimetry measurements above and inside test canyons amidst surrounding urban roughness. The study extended to two different canyon aspect ratios, in combination with different roof configurations on the surrounding buildings. To serve as a reliable basis for validation and testing of urban pollution dispersion codes, special emphasis was placed on data quality assurance.
