In the middle of the picture you can see forest floor with a cable trench and various cables running to a small measuring cabinet. Also visible are a Zarges box with a computer and an open file folder with occupancy plans, lying on the ground. At the right edge of the picture, a delicate green fern protrudes into the picture, otherwise one sees mainly thin bare tree trunks with a few individual leaves and brown ground covered with foliage.

Thann (Germany)

Meterological measurements and soil water investigations

Soil water measurements in a young mixed deciduous forest near Thann, where a small meteorological measuring station is set up concomitantly

Description & History

In May 2012 a small meteorological station was established near the village of Thann. The station is equipped with a Vaisala Weather Transmitter WXT52, which is a small lightweight compact multi-sensor instrument capable of measuring the main weather parameters: Air temperature and relative humidity, air pressure, wind speed and direction, precipitation (rain, its intensity and even hail). All data are logged and sent to Jena via modem.

The weather station serves as a source for additional information on soil water measurements in a forest area near the station. These investigations are carried out by the Gerd Gleixner Group.
