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, rather than using a physically-based (bottom up) process model. For more information, see the following open-access papers:

The GSCD was developed by Hylke Beck (Princeton University, Princeton, USA) in collaboration with Albert van Dijk (ANU, Canberra, Australia), Ad de Roo (JRC, Ispra, Italy), Diego Miralles (VU Amsterdam, The Netherlands), Jaap Schellekens (Deltares, Delft, The Netherlands), Tim McVicar (CSIRO, Canberra, Australia), Richard de Jeu (Transmissivity, Noordwijk, The Netherlands), and Sampurno Bruijnzeel (King’s College London, UK). The Global Runoff Data Centre (GRDC) and the US Geological Survey (USGS) are thanked for providing most of the flow data.
