Shanghai-2020 Dataset

It is released by the Shanghai Central Meteorological Observatory (SCMO) in 2020, records serval years of historical precipitation events in the Yangtze River delta area. The dataset contains a total of 43000 samples of precipitation events, of which 40000 samples for training and 3000 samples for testing. Each sample consists of 20 consecutive radar echo frames and lasts for 3 hours, where the first 10 frames are with intervals of 6 minutes and the last 10 frames are with intervals of 12 minutes. The echo frame has 460 * 460 resolution and covers 460km * 398km region. We additionally split out 3000 samples from the training set and use them for validation.该数据集由上海中心气象台（Shanghai Central Meteorological Observatory，SCMO）于2020年发布，记录了长江三角洲地区数年的历史降水事件。数据集总计包含43000条降水事件样本，其中40000条用于模型训练，3000条用于模型测试。每条样本由20帧连续的雷达回波帧组成，总时长为3小时，其中前10帧的时间间隔为6分钟，后10帧的时间间隔为12分钟。单帧雷达回波的分辨率为460×460，覆盖区域为460km×398km。我们额外从训练集中拆分出3000条样本，将其用于模型验证。
