The meteorological observations were started in 1976 and until 2007 were done manually. In April of 2007 an automatic weather station Weather Wizard III, Davis Instruments Corporation, USA was installed nearby. It measures air temperature at 2 m height, liquid precipitation, wind speed, and direction. The original version of the station was modified by a 32 Ah battery instead of the AC supply together with small backup battery. The charged battery lasts for approximate two months. The temperature probe was installed into an old wooden meteorological house (on the right). A small white shelter for wire connections is seen on the mounting tripod.
The soil temperature measurements were started in August of 2008. They are carried out at two depths: 10 cm (humus with surface roots) and 50 cm (sand with cobbles). This is done by using EL-USB-2 loggers (Lascar electronics).
The measurements of soil water contents were started in 2009. For this purpose, we have prepared the following equipment: Onset Hobo U12-006 external four channel voltage logger together with Watermark soil moisture sensors. To arrange equipment some soldering work was needed. The full list of the necessary equipment and prices is given below:
