Since the malicious destruction in summer 2000, the highest station is equiped with a hygro-thermograph and a rain gauge.
Both instruments draw automatically once a week upon a cylinder air-temperature, humidity and rainfall.
The diagram paper (acc. to DIN 58658) must be changed every week. (see also Glossary)
Measurements are stored in a data logger (memory module) with a capacity of 2339 data frames. A special interface is used to transmit the data from the module to the PC. After converting the data into the ASCII-format, a further computer-aided analysis of data can be done with software e.g. Excel, Access etc.
To minimize data loss the facilities are operated with accumulators buffered by solar energy. Electric tension and capacity will be kept on a constant level by a regulator-unit.

The climatic stations (Home Station, Valley Station) are equiped with
digital instruments recording on an hourly basis.
The following parameters are measured:
The measured values are stored hourly by the data logger (Memory module). The capacity of the data logger counts a maximum of 2339 data frames (= 32 Kb).
Construction and functionality of the data logger
The data logger consists of a microcontroller-chip that is placed in a plastic box. The storage capacity of the chip is at about 32 kilobytes (Kb), corresponding to 2339 data frames (1 frame consists of 14 bytes). Adjusted to hourly measurments, the chip is able to record data within a period of 97 days and 12 hours. From the case of the memory module consists of a flat cable with a plug connector. This plug connector. The connecting plug serves for the connection with the main module of the station during the data recording. To import data into the PC a periperal interface adapter is used. The micro tracer on the top of the case of the module serves for the different modes of operation.
Storage capacity: 32 kB, 2340 frames
