South China Convection Initiation Dataset (2018-2023)

本数据集提供 2018-2023 年华南地区的对流初生 CI 样本(8,607 个)及其附近 2.5° 范围内随机的一个非CI样本(8,607 个)。数据包括 CI 和非CI的位置、全生命周期路径(含35 dBZ 轮廓),以及所有样本的前后 30 min 的雷达回波演变图。所有公开时间均使用 UTC。其中,Labels_CI.csv 保存 CI 样本的位置、类别、个例编号和样本时间;Labels_nonCI_nearest(UTC).csv 保存非CI样本的位置、类别、个例编号和样本时间;Image.zip 保存雷达反射率前后 30 min 演变图;Tracking_CI.zip 保存 CI 全生命周期路径。【具体细节见Readme.html】 This dataset provides 8,607 convection initiation (CI) samples over South China during 2018-2023 and one randomly selected non-CI sample within 2.5° of each CI sample (8,607 samples). It includes CI and non-CI locations, full life-cycle paths (including 35 dBZ contours), and radar echo evolution images from 30 min before to 30 min after all samples. All released times use UTC. Specifically, Labels_CI.csv stores CI sample location, class label, case ID, and sample time; Labels_nonCI_nearest(UTC).csv stores non-CI sample location, class label, case ID, and sample time; Image.zip stores radar reflectivity evolution images from 30 min before to 30 min after the samples; Tracking_CI.zip stores CI full life-cycle paths. 【Details please see Readme.html】
