Rain gauge and radar rainfall comparison dataset (four events)

This dataset contains 30-minute accumulated precipitation measurements from rain gauges and two radar retrieval products (SPAR and SPOL) during four severe convective events over Fuzhou (31 August 2022, 7 August 2023, 14 August 2024, and 1 August 2025). Radar-derived intensities (mm/h) were converted to 30-minute accumulations (mm) by averaging half-hourly values and multiplying by 0.5. Columns: station_code, half_hour, PRE_sum (gauge, mm), SPAR_radar (mm), SPOL_radar (mm). Data in CSV format.
