Schematic overview of the generation of global curve number (GCN250) product. Three main steps are illustrated: (1) CN look-up table is created based on mapping ESA CCI-LC land cover classes into National Engineering Handbook – Part 630 Hydrology land cover classes (NEH-630); (2) ESA CCI-LC 2015 300 m raster is resampled to spatial resolution ~250 m (ESA-CCI LC 250 m); (3) CN values (GCN250) are mapped at ~250 m spatial resolution based on the hydrologic soil groups dataset (HYSOGs250m), CN look-up table (step 1), and the resampled ESA CCI-LC 250m raster (step 2).
