Summary

• What is new: A novel deep convolutional neural network model incorporating skip connections, attention blocks, and auxiliary data concatenation for downscaling precipitation data.
• Why this is important: The need for accurate local-scale precipitation prediction to manage water resources efficiently and mitigate flood risks, given the limitations of current climate models in resolution and computational demands.
• What the research proposes: Developing a high-resolution precipitation downscaling method using advanced deep learning techniques to improve the accuracy of rainfall forecasts.
• Results: Demonstrated superior performance over existing climate downscaling methods in terms of Mean Absolute Error, Root Mean Square Error, Pearson Correlation, structural similarity index, and forecast indicators.
