A Station for botanical and dendrochronological research was founded in Vaišnoriškė village in 1976. The station was aimed at the environmental monitoring. A small village Vaišnoriškė is located in the northeastern Lithuania (National Park of Aukštaitija). The climate in this region is more continental in comparison to other regions of Lithuania. The key features are: lower amount of precipitation and wind speed, colder winters and delayed spring in comparison to other regions. The climate is influenced by forested land with many lakes, which forms specific macro-climatic conditions. E. Šimkūnienė is responsible for the observations. Please visit our bibliography page for publications.
The following observations have been carried out:
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:
