This archive contains estimates of runoff to the ocenas for all river outlets globally, excluding Greenland and Antarctica, based on routing through the simulated topological network at 30-minute spatial resolution (STN-30p, version 6.01; 2004–07) flow network [Vörösmarty et al. 2000; downloaded from Water Systems Analysis Group (2007)] at 1/2-degree latitude-by-longitude resolution using the Lohmann et al. (1996, 1998) routing model. The data set is a hybrid of simulated and observed streamflow for 4 model-method combinations, as described in Clark et al., J. Hydrometeor. (2015).
