GCN250, global curve number datasets for hydrologic modeling and design

Global Curve Number Datasets in Geotiff format at the 250m spatial resolution for average, dry, and wet antecedent runoff conditions based on HYSOG250m hydrological soil group dataset and the ESACC-CI 2015 global land cover dataset at the 300m spatial resolution. The R-code (GCN250m.R) for generating the curve numbers from the soils and the land cover datasets is also provided.

本数据集为基于HYSOG250m水文土壤组数据集以及空间分辨率为300米的ESACC-CI 2015全球土地覆盖数据集，生成的250米空间分辨率GeoTIFF(GeoTIFF)格式全球曲线数数据集，涵盖平均、干旱及湿润三种前期径流条件下的曲线数结果。此外还提供了用于从土壤与土地覆盖数据集生成曲线数的R代码脚本GCN250m.R。
