Climate model “family trees” reduce biases in study results

MISU researchers Peter Kuma, Frida Bender and Aiden Jönsson have developed a computer-based genealogy of climate models, with focus on atmospheric processes, that will help researchers account for the code relationships among different models. By applying these statistical methods, biases in study results can be reduced.
