Abstract: The study presents the results of an analysis of mean daily values of soil temperature measured with mercury thermometers and electronic sensors during the period 2000–2009 in Wroclaw-Swojec Observatory. Daily averages were calculated from three measurements a day with standard devices and in two ways from automatic data: from the same terms and from all 24 hours. Linear regression, frequency and significance of differences, time series analysis (i.e. autocorrelation analysis and seasonal decomposition using the additive model) were performed to determine whether a change in the method of calculating mean daily values might decrease the differences between the two methods.
