Dataset of high-resolution (3 hour, 10 km) global surface solar radiation (1983-2018)

The dataset is a nearly 36-year (1983.7-2018.12) high-resolution (3 h, 10 km) global SSR (surface solar radiation) dataset, which can be used for hydrological modeling, land surface modeling and engineering application. The dataset was produced based on ISCCP-HXG cloud products, ERA5 reanalysis data, and MODIS aerosol and albedo products with an improved physical parameterization scheme. Validation and comparisons with other global satellite radiation products indicate that our SSR estimates were generally better than those of the ISCCP flux dataset (ISCCP-FD), the global energy and water cycle experiment surface radiation budget (GEWEX-SRB), and the Earth's Radiant Energy System (CERES). This SSR dataset will contribute to the land-surface process simulations and the photovoltaic applications in the future. The unit is W/㎡, instantaneous value.

Data file naming and use method

Each data file is named as (e.g., where YYYY is the four-digital year, MM is the two-digital month, DD is the two-digital day, HH is the two-digital hour, that means one file contains data for only one hour, additionally, .nc is the file name suffix which indicates that the data were stored as NetCDF format; For more information about NetCDF, please see
