1-km Gridded Meteorological Dataset for the Huang–Huai–Hai Region, China (2010–2020)

1-km Gridded Meteorological Dataset for the Huang–Huai–Hai Region, China (2010–2020) Author: Qian LongYear: 2026DOI: 10.5281/zenodo.22100112 Dataset description This dataset provides monthly gridded meteorological data at a spatial resolution of 1 km × 1 km for the Huang–Huai–Hai region (HHHR), China, during 2010–2020. The dataset was generated from daily observations recorded at 535 national meteorological stations using a generalized additive model (GAM) for spatial interpolation. The dataset includes the following meteorological variables: Maximum air temperature at 2 m (Tmax) Minimum air temperature at 2 m (Tmin) Solar radiation (Rs) Relative humidity (RH) Wind speed at 10 m (WS) Precipitation (Pre) The gridded data are provided in GeoTIFF (.tif) format and organized by meteorological variable, year, and month. For example: Pre_2010_01.tif represents the gridded precipitation dataset for January 2010. Spatial and temporal information Region: Huang–Huai–Hai region, China Period: 2010–2020 Temporal resolution: Monthly Spatial resolution: 1 km × 1 km File format: GeoTIFF (.tif) Interpolation method: Generalized Additive Model (GAM) In the associated study, the 2011–2020 subset of this dataset was used as meteorological input for GAEZ-based crop potential-yield simulations and water-availability assessments.
