Temporal variability of temperature in cave system

Hourly monitoring of cave temperature has begun in 2007 at 4 places. Measurement places present impact of different factors, e.g. distance of the cave entrance (close vs. far), degree of ventilation (strongly vs. poorly ventilated passages), impact of tourism (touristic vs. non-touristic passages), type of influental entrance (upper vs. lower). Also other smaller but older temperature datasets (1933-1937) are available. Temperature can be compared with other parallelly measured parameters, like relative humidity, cave air CO2 concentration, wind direction and speed etc.
