Map of temperature distribution on the surface of solid ground 1: 100,000
The map shows the average annual temperatures on the surface of solid ground for the area of Slovenia. A raster layer of 30-year average (1981-2010) air temperatures measured 2 m above the ground was used as input data. The surface temperature of solids was calculated by adding 1 ° C to the values of air temperatures in the continental part of Slovenia and 1.2 ° C in the coastal part of Slovenia. The value for mainland Slovenia is calculated as the average of the differences between the trend lines of the average air temperature (2 m) and the average soil temperature (-2 cm) between altitudes of 0 m (1.3 ° C) and 2864 m (0.7 ° C). For coastal Slovenia this value is only estimated due to insufficient number of data.
The purpose of the map is a spatial presentation of temperature distribution on the surface of solid ground. Surface temperature represents one of the key parameters for calculation of exploitation potential for shallow geothermal sources.
Use: + Research and use of shallow geothermal energy for heating and cooling the facilities + Preparation of professional bases for geothermal heat pump systems planning + Spatial planning + Guidelines for the development of local energy concepts - For coastal area of Slovenia, the value is only estimated due to insufficient number of data
