High-resolution radar–gauge merged precipitation dataset for South Korea (2016–2024): Part 2

This dataset provides high-resolution radar–rain gauge merged precipitation data over South Korea. The dataset covers the period 2021–2024 (part 2 of a two-part dataset spanning 2016–2024) and was generated by merging radar-based precipitation estimates with ground-based rain gauge observations using a radial basis function (RBF)-based interpolation method. The data are provided at a spatial resolution of 0.5 km and a temporal resolution of 10 minutes. The dataset is distributed as monthly compressed archives (YYYYMM.tar.gz). Each archive contains NetCDF files for individual 10-minute precipitation fields, organized in the directory structure:YYYYMM/DD/YYYYMMDDHHmm.nc Radar input data were obtained from the Korea Meteorological Administration (KMA) API Hub and are subject to KMA data policy. Rain gauge data were collected from ASOS and AWS networks operated by KMA. This dataset is suitable for hydrological modeling, extreme rainfall analysis, flood forecasting, and climate research.
