I made a little animation showing the geospatial distribution of weather stations over time. The temperature range is from -70°C (dark blue) over 0° (white), 10°C (yellow), 32°C (red) to 40°C (dark red). The video goes through 3 loops showing the mean temperature (MT), the summer mean temperature (SMT) and the winter mean temperature (WMT).

The second charts shows the percentage of weather stations in certain latitude regions over time:
