Data processing


The climatic stations (Home Station, Valley Station) are equiped with digital instruments recording on an hourly basis.

Seven meteorological parameters are registered including date and hour. With the aid of an interface data can be transmitted to the PC and also converted into the ASCII-Format. The analysis of the data will be done by a user-defined Excel-Sheet that calculates automatically the values of all parameters daily and monthly. Diagrams are realized such as monthly and annual progress of temperature and precipitation. In additional, diagrams of thermoisoplethes show graphically the progress of temperature by combining hourly and daily of measured values.

Precipitation is collected in rain gauges according to Prof. Hellmann (WMO-standard) with a sectional area of 200 cm2. Hourly measurements of rainfall guarantee a detailed study of heavy rainfall.

The following parameters are measured:

  • Temperature [°C]
  • Humidity [r.F %]
  • Air-Pressure [hPa]
  • Global radiation [Lux]
  • Wind direction [° from N]
  • Wind velocity [kmh-1]
  • Precipitation

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.
