摘要: Abstract Nitrogen monoxide (NO), nitrogen dioxide (NO 2 ) and ozone (O 3 have been measured downwind (0–450 m) from two line sources in a suburban environment set of initial experiments designed to investigate the role chemistry determining the partitioning NOx into NO ability commercial modelling package (ADMS) reproduce speciated concentrations. concentrations decrease more rapidly than as is removed both by dilution chemical reaction with ozone. Whilst dominant form at roadside, decay slowly (due to production higher background levels) typically forms majority 50–100 m source. For studies input were match experimental site. The decays can be accurately reproduced ADMS dispersion model only when transformation taken account. When estimated directly traffic flow measurements, modelled tends underestimate value.
