The proposed study aims to improve the accuracy of local climate information by developing a stochastic downscaling technique using Generative Adversarial Networks (GANs). This is crucial for estimating uncertainty and characterizing extreme events, which are critical for climate adaptation. The current methods have been found to suffer from underdispersion, failing to represent the full distribution of possible outcomes. To address this issue, three approaches are proposed: injecting noise inside the network, adjusting the training process to account for stochasticity, and using a probabilistic loss metric. The effectiveness of these approaches is evaluated on both synthetic and realistic datasets, with promising results.

This study aims to improve our understanding of climate by developing more accurate local climate predictions. Right now, it’s hard to get good information about what the weather will be like in different areas because we’re using old methods that don’t account for all the possible outcomes. The researchers are trying three new approaches to fix this problem: adding some randomness to the model, adjusting how the model is trained, and using a special type of math to make sure the model is accurate. They tested these ideas on both fake data and real data and found that they worked pretty well.
