Observation-based MAP OF MEAN RUNOFF
A global map of mean annual runoff (0.04° resolution) based on streamflow observations from 1651 large catchments (>10,000 km²). The map can be considered an update of the 0.5° UNH/GRDC Composite Runoff Fields dataset, which was based on observations from only 663 catchments. The map including documentation is available here.
