Deterministic nowcasting of geostationary satellite infrared brightness temperature using 3D U-Net diffusion model

Abstract We present a generative modeling approach for nowcasting infrared (IR) brightness temperatures (Tb) from geostationary satellite observations (~ 10.8 μm) that couples a denoising diffusion probabilistic model with a 3D U-Net backbone. Using SEVIRI observations, the model ingests six hours o...
