- Abstract: This paper presents a solution to the Weather4cast 2022 Challenge Stage 2.
The goal of the challenge is to forecast future high-resolution rainfall events
obtained from ground radar using low-resolution multiband satellite images. We
suggest a solution that performs data preprocessing appropriate to the
challenge and then predicts rainfall movies using a novel RainUNet. RainUNet is
a hierarchical U-shaped network with temporal-wise separable block (TS block)
using a decoupled large kernel 3D convolution to improve the prediction
performance. Various evaluation metrics show that our solution is effective
compared to the baseline method. The source codes are available at

We propose RainyScape, an unsupervised framework for reconstructing clean scenes from a collection of multi-view rainy images.
Based on the spectral bias property of neural networks, we first optimize the neural rendering pipeline to obtain a low-frequency scene representation.
We jointly optimize the two modules, driven by the proposed adaptive direction-sensitive gradient-based reconstruction loss.
