A dual-channel CRDS system for NO2 and NO detection is reported. The detection limits of the developed CRDS system for NO2 and NOx measurements are estimated to be about 0.030 ppb (1σ, 1 s) and 0.040 ppb (1σ, 1 s), respectively. The measurements of on-road vehicle emission plumes by this mobile CRDS instrument show the different emission characteristics in the urban and suburban areas of Hefei. The instrument provides a new method for retrieving fast variations in NO and NO2 plumes.
