Gempen
The long-term energy
balance station "Gempen" is located approximately 15 km South of
Basel in the Jura mountains. This station of the University
of Basel is similar to Basel - Lange Erlen
and operated since 1991 over agricultural land. The station is located on
a exposed mountain plateau that is 500m higher than the city of Basel.
Therefore in most cases the station indicates
the synoptic wind forcing.
In wintertime the station can be on top
of the inversion, which covers the Rhine-plane.

At
the 10m tower "Gempen" profiles of wind and temperature /
humidity are operated. Additionally soil temperature (4 levels) and
soil heat fluxes (3) are measured. 17.05.2000. |
