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.
