ChinaEpan0.05°: a high-resolution gridded dataset for continuous daily D20 and E601 pan evaporation across China (1960–2024)
Listed in ScienceDB
This dataset presents continuous daily gridded data of D20 and E601 pan evaporation (Epan) at 0.05° spatial resolution across China from 1960 to 2024.
Description
Based on observations from 2479 meteorological stations, the dataset addresses severe data gaps (29.92% for D20 and 91.12% for E601) using a hierarchical interpolation strategy (for D20) and an innovative three-stage framework (for E601), combined with Gaussian process regression for scale conversion.
Validation shows reliable accuracy: D20 (RMSE=1.08 mm d-1, R2=0.77) and E601 (RMSE=0.68 mm d-1, R2=0.70), effectively capturing spatial heterogeneity of Epan in China. The dataset fills a critical gap in long-term continuous daily Epan data, providing essential inputs for hydrological cycle research under climate change. It contains 47,484 files (23,742 for D20 and 23,742 for E601), named as "d20_year_month_day.tif", such as "d20_19610101.tif".
