During Summer 2002 (IOP) a pneumatic 16m tower was installed with 3 levels of sonic anemometers and full radiation components at tower top over this "European suburban" surface. The site was operated by ETH Zurich, University of Basel and the Bulagarian National Institute of Meteorology and Hydrology.

The suburban area of Allschwil
consists of a relatively homogeneous city part with older single and row houses and small streets. It is about 1 km westward of the urban site "Basel-Spalenring", and at least 1 km away from any rural area. In the backyards are many trees and scrubs. Just below the tower there is a large flat roof. |
