Truck Chasing Experiment

During a 4-day measurement project in June 2005, the mobile laboratory (FML) of the Ford Forschungszentrum Aachen (FFA) was equipped with the following aerosol and gas-phase instrumentations: An Aerodyne Quadrupole Aerosol Mass Spectrometer (Q-AMS), a scanning mobility particle sizer (SMPS, TSI Inc.), a condensation particle counter (TSI 3022), a particulate black carbon monitor (AVL 483 Micro Soot Sensor), NO_x and CO₂ gas analyzers and meteorological base parameter (temperature and relative humidity) sensors.
A total of 6 measurement drives were performed, each of which about 3 hours in duration. The measurements took place in the vicinity of Aachen, Germany, mostly on motorways (A4, A44, A61), on regional roads in a rural environment, in the inner city of Aachen, and partly in suburban areas or smaller cities. The focus of the measurements was the chasing of individual trucks under cruising conditions, but also background aerosol on motorways, rural regional roads and in the inner city of Aachen was sampled.
