Video series on climate modeling on HYPERRAUM.TV

Jan 27, 2021

In November and December 2020, the German platform for science and technology HYPERRAUM.TV published a five-part video series on fundamental questions about climate modeling and research. The short videos conceived by the journalist Susanne Päch have been created in cooperation with the DKRZ, the Cluster of Excellence CLICCS / Center for Earth System Research and Sustainability (CEN) at the University of Hamburg, the European Space Agency ESA, and the US Federal Agency for Space and Aviation NASA or the University of Hanover.

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.

The five parts of the series (in German only) on questions of climate research and modeling:

  1. Beherrschung des Chaos (Mastery of chaos): The climate system between chaotic local phenomena and deterministic global drive of carbon dioxide emissions
  2. Down-, Up- und Multiscaling (Down-, Up- and Multiscaling): The scaling of space and time in climate models
  3. Zahlen und Zeichen (Numbers and fugures): From equation to visualization: the seven most important work steps in climate modeling
  4. Von Zahlen zum Bild (From numbers to images): Numerically calculated climate models and how they can be visualized
  5. Prüfstand Klimamodel (Climate put in the test bench: The validation of climate models with historical data and international analysis
