Andean Glacierized Catchment (Andean-GC) dataset
收藏资源简介:
A comprehensive streamflow dataset for glacierized basins across the Andes mountains (glacier area > 0.1%), integrating data from Chile, Peru, and Argentina. The dataset combines institutional streamflow records with basin characteristics including topographic, climatic, and land cover attributes, along with historical ERA5 climate data for hydrological analysis and modeling.
