Global Streamflow Characteristics Dataset


The Glob­al Stream­flow Char­ac­ter­is­tics Dataset (GSCD) con­sists of glob­al maps of 17 stream­flow char­ac­ter­is­tics, such as base­flow index, runoff coef­fi­cient, and flow per­centiles, pro­vid­ing infor­ma­tion about runoff behav­ior for the entire land sur­face includ­ing ungauged regions.
The maps are unique in that they were derived using a data-dri­ven (top down) approach based on stream­flow obser­va­tions from thou­sands of catch­ments around the globe, as opposed to a phys­i­cal­ly-based (bot­tom up) process mod­el. For more infor­ma­tion, see the fol­low­ing open-access papers: 


The lat­est ver­sion of the GSCD (ver­sion 2.0) can be down­loaded here (372 MB). See the tech­ni­cal doc­u­men­ta­tion for the ver­sion his­to­ry. The data are released under the CC BY-NC 4.0 license and thus may not be used for com­mer­cial pur­pos­es. If the dataset forms a key com­po­nent of your research, we kind­ly ask that you give us the oppor­tu­ni­ty to com­ment on your results pri­or to pub­li­ca­tion. By using the GSCD in any pub­li­ca­tion you agree to cite the above-men­tioned papers.
