Workshop: Tackling Climate Change with Machine Learning

Deep learning-based bias adjustment of decadal climate predictions

Reinel Sospedra-Alfonso · Johannes Exenberger · Marie McGraw · Trung Kien Dang


Decadal climate predictions are key to inform adaptation strategies in a warming climate. Coupled climate models used for decadal predictions are, however, imperfect representations of the climate system leading to forecast biases. Biases can also result from a poor model initialization that, when combined with forecast drift, can produce errors depending non-linearly on lead time. We propose a deep learning-based bias correction approach for the post-processing of gridded forecasts to enhance the accuracy of decadal predictions.
