AGToLightM Training Data

The raw data utilized in this study, including FY-4B satellite imagery and ground-based lightning observations, are retrieved from the "CMA-Tianqing" system of the China Meteorological Administration, which is not publicly accessible due to security and data policy restrictions. However, the preprocessed datasets used for model training and validation in this work have undergone a series of quality control and normalization procedures. A representative subset of these processed data, focusing on the East China research area, is provided as a sample to demonstrate the data structure and processing workflow.
