Observation on data availability/gaps

Discharge and runoff estimates for HydroATLAS are based on long-term (1971–2000) average ‘naturalized’ discharge and runoff values provided by the state-of-the-art global integrated water balance model WaterGAP (Döll et al. 2003, model version 2.2 as of 2014). The WaterGAP data were spatially downscaled from their original 0.5 degree pixel resolution (~50 km at the equator) to the 15 arc-second (~500 m) resolution of the HydroSHEDS river network using geo-statistical techniques (Lehner and Grill 2013). The HydroATLAS database is distributed in large file sizes due to the enriched attribute information.
