Abstract:

During BTEX a MFAS mini–SODAR (manufactured by Scintec, Germany) was installed on the roof of the incinerator of Bolzano (46.468463 N, 11.308782 E, 245 m ASL) at 40 m AGL. In particular, the SODAR was installed close to the chimney of the incinerator, in order to monitor the wind field at the outlet of the stack, where emissions are released into the atmosphere. The SODAR investigated an atmospheric layer 400 m-deep along 38 10 m-spaced vertical levels. Indeed, the lowest datum is provided at 30 m above the antenna, i.e.

70 m AGL and 315 m ASL, whereas the highest one is provided at 400 m above the antenna, i.e. 685 m ASL. Actually, at each vertical level, the SODAR provides a measure averaged over an atmospheric layer 30 m–thick and centered at the elevation of the level.

Raw data were processed by means of the software APRun, provided by Scintec, in order to obtain the vertical profiles of:

1. mean wind quantities, i.e. wind speed components, wind intensity, wind direction;

2. standard deviations of the wind speed components;

3. back scatter.

Due to the environmental noise affecting the site, raw data were processed and averaged over a time–window of 30 min, in order to obtain reliable profiles of the above quantities. The time-stamp refers to the end of the averaging period.
