Cave microclimate is prone to important changes in certain passages due to intensive tourism. Monitoring the climatic parameters (air temperature, CO2) in Postojna-Planina Cave System helps to have a proper picture of the impact of tourism for the cave. It is very useful to compare if additional increase of temperature is associated with the changes at the surface climate. The dataset comprises two types of daily mean air temperature data: 1) the daily mean air temperature data (°C) measured in “Lepe jame” cave passage from Postojna Cave, counting constantly a very high number of tourists; the measurements were made in the same point, by three sensors placed at three different height points (in the wall cracks [T1], at ceiling level [T3], and at 2 m height [T2]). Values are recorded at 10 min intervals and then averaged for daily data (the dataset for Lepe jame cave passage is provided by MEIS Environmental consulting d.o.o. (http://www.meis.si/) while the data are part of the project "Assesment of natural and antropogenic processes in micrometeorology of Postojna cave system by numerical models and modern methods of data aquisition and transfer" [https://izrk.zrc-sazu.si/en/programi-in-projekti/assesment-of-natural-and-antropogenic-processes-in-micrometeorology-of-postojna#v]; 2) the surface daily mean air temperature measured at 2 m height (°C) at the Postojna meteorological station, as part of the national network of meteorological stations within the Environmental Agency of the Republic of Slovenia (ARSO; http://meteo.arso.gov.si/).

GIS thematic data on human activity and infrastructure in the Park, covering a.o. (1) tourism infrastructure and activity (trails, shelters, campsites, caves accessible to tourists, museums, sports and leisure infrastructure, educational facilities, etc. - as well as tourist traffic counts); (2) roads and other transport facilities (incl. cable car); (3) buildings (dense housing and individual objects), (4) geodetic/cadastral layers, land parcels, (5) cultural heritage (historic monuments incl. religious objects, remnants of past mining activity, historic sheep/cattle grazing infrastructure such as shepherd huts, etc.); (6) other infrastructure (e.g. power lines, water takeup points, meteo stations, etc.). Also, data on anthropogenic pressure: environmental impact and damage of human activity available.
