We have radar echo data in Yinchuan, Ningxia for 2018 and 2019, which is collected every six minutes. Due to the infrequent occurrence of precipitation, radar echo data from 84 rainy days were selected to form our dataset. We first processed the original data with noise reduction, and then used a sliding window of length 20 to evenly divide the training and test sets in a 4:1 ratio. The details of how the dataset was produced are clearly described in the paper. precipitation is the final dataset. Due to the size of the original dataset, only three days of the radar echo precipitation data are provided here for testing purposes.
