 abstract={This study presents the results of an analysis of mean daily values for soil temperature measured using mercury thermometers and electronic sensors during the period 2000-2009 at the Wrocław-Swojec Observatory. Daily averages were calculated on the basis of three measurements a day made using standard devices, as well as 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 reduce the differences between the two methods.},
