Air temperature at the upper forest line in the Tatras, station Rynna Dno Las

For 12 months, air temperature was measured at a height of 2 m above the ground at the upper forest line in the Tatras. The aim of these studies was to show the relationship between terrain forms (concave and convex) on air temperature. The lowest air temperature value was characteristic of concave terrain forms and in them the upper forest line ran lower than on convex terrain forms.
