Conditional diffusion model produces high-resolution temperature maps from sparse station data
Researchers have introduced a conditional diffusion framework that refines coarse ERA5 reanalysis fields into fine-scale air temperature estimates by incorporating sparse ground-station measurements. The approach is designed to capture terrain and land-surface contrasts that coarse products miss, with the goal of improving local heatwave hazard assessment in areas with limited sensor coverage.
