Basel
- Messe
This small energy
balance station was deployed on the roof of a
parking building during the IOP
in Summer 2002 by TU
Dresden. The site is located 500 m South-East of Basel-Sperrstrasse
in the dense urban area around "Messe Basel". The 170 by 80 m
large concrete roof is used as a parking lot but was closed to public during
the period of measurements. During the tracer
release experiments tethered balloons were operated at this site.

The
Eddy-Covariance System (including a fast hygrometer) was mounted to a
pole on the top of the roof. The CNR1 - radiometer provides full
radiation components. Storage heat flux was determined using heat flux
plates that were modified with same surface properties (25.6.2002) |
