Reconstructing 10-km-resolution direct normal irradiance dataset through a hybrid algorithm

The 41-year (1982-2022) daily DNI dataset (CHDNI) reconstructed in this study has been uploaded, and stored in netcdf format.  The one-year dataset comprises daily DNI estimates for either 365 or 366 days, with individual data files separately organized by year. Each daily file is stored in mat format and labeled as "pred_xxxxxyymm," where ‘xxxx' denotes the year, ‘yy' represents the month, and ‘mm' stands for the day. The geographical scope of CHDNI dataset spans from 3°N to 54°N in latitude and from 72°E to 136°E in longitude. The mat matrix, encapsulating the data, is configured with dimensions of 361 rows and 641 columns, measured in W/m2.
