%X These gridded surface cloud fractional radiation nuclei (GCF-CRKs) were created by integrating refined estimates of sinking surface shortwave radiation (DSSR) and high-precision cloud fractions (CF). Using these GCF-CRKs, the spatiotemporal characteristics of Arctic surface shortwave CRE were estimated over a 21 year period (2000-2020).  There are five separate files in total. SFC_SW_Kernel_Src.nc "is used for CRK of all clouds," SFC_SW_0wcloud_Kernel_Src.nc "is used for CRK of low-level clouds," SFC_SW_idlowcloud_Kernel_Src. nc "is used for CRK of mid to low-level clouds," SFC_SW_idhigcloud_Kernel_Src.nc "is used for CRK of mid to high-level clouds, and" SFC_SW_ighcloud_Kernel_Src.nc "is used for CRK of high-level clouds. The four cloud layers are derived from four pressure layers (from the surface to 700 hPa, 700-500 hPa, 500-300 hPa, and 300-50 hPa, representing low clouds, medium low clouds, medium high clouds, and high clouds, respectively) according to the CERES-SYN stratification criteria.The file format is netcdf4, created by Matlab. To read these files, any software that supports netcdf4 can be used. These documents only cover sunny months from April to September between 2000 and 2020, with a longitude range of -180 °~180 ° and a latitude range of 60 ° N~90 ° N.
