Evaluating Cross-region Generalization for Wavelet-Diffusion Precipitation Downscaling
Diffusion models have shown strong potential for kilometer-scale precipitation downscaling, but their performance in geographically unseen regions and event regimes remains insufficiently understood. Building on the wavelet diffusion model (WDM) framework, this study evaluates cross-region and cross-event generalizatio...
