<p><strong>Abstract.</strong> The paper describes the dataset of concentrations and related meteorological measurements collected during the field campaign of the Bolzano Tracer Experiment (BTEX). The experiment was performed to characterize the dispersion of pollutants emitted from a waste incinerator in the basin of the city of Bolzano, in the Italian Alps. As part of the experiment two controlled releases of a passive gas tracer (sulfure exafluoride, SF<sub>6</sub>) were performed through

Samples of ambient air were collected at target sites with vacuum-filled glass bottles and polyvinyl fluoride bags, and later analyzed by means of a mass spectrometer (detectability limit 30&amp;thinsp;ppt<sub>v</sub>). Meteorological conditions were monitored by a network of 15 ground weather stations, 1 microwave temperature profiler, 1 SODAR and 1 Doppler Wind-LIDAR. The dataset represents one of the few examples available in the literature concerning dispersion processes in a typical mountain valley environment and provides a useful benchmark for testing atmospheric dispersion models in complex terrain.
