The series explains for non-experts how, for example, climate models are validated on the basis of historical data and that climate models uses simplifications of mathematical equations, which nevertheless describe mathematically correct the chaotic systems on the smallest scale. An overview shows the essential work steps necessary emulate the earth system with numerical models. In the episode „Von Zahlen zum Bild (from numbers to images)“, the Michael Böttinger, leader of the visualization group at DKRZ, demonstrates how to visualize the resulting data of these climate model calculations so that scientists can interpret them.
