In our Climate Portal, you will find measurement data from numerous weather stations that we have processed in various ways. You can search for a weather station using the map or the search mask. We aim to visualize these data through various representations to facilitate the identification of climate trends. Such trends become more discernible with longer and more comprehensive measurement series. Especially with long-term data spanning many decades, you will notice that the temperature trend is upwards. Of course, you can also simply view historical data using these representations.
For the beginning, we have chosen three different visualizations for three different parameters (temperature, precipitation, sunshine hours):
Lines
The temperature data here always refers to the daily average temperature. You can display various climate reference periods and choose comparison years. This will allow you to easily see whether the average temperature was above or below the selected long-term average.
For precipitation and sunshine hours, you will see a yearly total. Here too, you can determine whether the chosen year was wetter/drier or sunnier than average. Note that sunshine duration has not been measured for as long as temperature and precipitation at most weather stations.
Heatmap
In the heatmaps, you can view the measurement values both as absolute values and as anomalies (K=°C). Anomalies represent deviations from the selected climate reference period (for example, 1991-2020). For temperature, the displayed data is again based on daily average temperature - for precipitation and sunshine hours, it represents a total sum.
Stripes
In the stripes view, you can display all available years or the four seasons. Trends over several decades can be discovered best in long-term data series. Anomalies (K=°C) are shown for all three parameters (temperature, precipitation, sunshine). The anomaly (deviation) is with respect to the selected climate reference.
