Homogeneous data series since 1864 are provided by MeteoSwiss through the opendata.swiss platform. The series consist of monthly means of temperature and precipitation for a total of 14 weather stations in Switzerland. To allow for a comparison of different months and stations a standard score is applied to these series. For a reference period (e. g. the climatological normal period 1980 - 2010) mean and standard deviation are determined per month of the year and station. The data set is then “normalised” with it. The resulting visualisation illustrates the distinct temperature rise during the last decades (global warming). Further, the most extreme months are highlighted in the plot.
