Abstract

Even though soil temperature in urban environment influences a range of processes, it has been studied
rather sparsely in comparison with surface temperature or air temperature. Our research extends the
soil temperature observation in Olomouc (Czechia) and uses semi-stationary measurement to describe
detailed spatial variability of soil temperature in the area of a medium-sized Central European city. Differences in soil temperature 20 cm below grass-covered surface may exceed 3°C due to soil type, shadow cast by buildings and grass characteristics, which means that the representativeness of the data
on soil temperature from a meteorological station within a city may be limited. Further research and a
conceptual approach towards the study of soil temperature in urban landscape is needed.
