Global Hydrologic Curve Number

The GCN250 is a globally consistent, gridded dataset defining CNs at the 250 m spatial resolution from new global land cover (300 m) and soils data (250 m). GCN250 represents runoff for a combination of the European space agency global land cover dataset for 2015 (ESA CCI-LC) resampled to 250 m and geo-registered with the hydrologic soil group global data product (HYSOGs250m) released in 2018. The potential application of this data includes hydrologic design, land management applications, flood risk assessment, and groundwater recharge modeling.

This dataset is now available in the GEE community catalog. you can find it here https://samapriya.github.io/awesome-gee-community-datasets/projects/gcn250/. Thank you for contributing to the catalog, I added the code link for the app and made minor edits at best. Look forward to more contributions :)
