A continuous variation of thermal energy, presented as air temperature, is registered by a ground-based network. However, an insufficient number of stations does not allow for the presentation of the spatial distribution of these values on the meso or micro scales. For this reason data recorded by a satellite sensor were used to analyse the variation in thermal energy on both spatial and temporal scales. Five satellite images were selected to represent seasons of the year and the thermal conditions of these days were validated. Apart from in August they presented typical thermal conditions for the month, thereby allowing the relation between different types of land cover and surface temperature in satellite acquisition time to be analysed.
Keywords: air temperature, surface temperature, satellite data, type of land cover
