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-dri¬≠ven (top down) approach based on stream¬≠flow obser¬≠va¬≠tions from thou¬≠sands of catch¬≠ments around the globe, as opposed to a phys¬≠i¬≠cal¬≠ly-based (bot¬≠tom up) process mod¬≠el. For more infor¬≠ma¬≠tion, see the fol¬≠low¬≠ing open-access papers: 


The lat¬≠est ver¬≠sion of the GSCD (ver¬≠sion 2.0) can be down¬≠loaded here (372 MB). See the tech¬≠ni¬≠cal doc¬≠u¬≠men¬≠ta¬≠tion for the ver¬≠sion his¬≠to¬≠ry. The data are released under the CC BY-NC 4.0 license and thus may not be used for com¬≠mer¬≠cial pur¬≠pos¬≠es. If the dataset forms a key com¬≠po¬≠nent of your research, we kind¬≠ly ask that you give us the oppor¬≠tu¬≠ni¬≠ty to com¬≠ment on your results pri¬≠or to pub¬≠li¬≠ca¬≠tion. By using the GSCD in any pub¬≠li¬≠ca¬≠tion you agree to cite the above-men¬≠tioned papers.
