Years of Record: 1948/12 to 2006/11
The Coordinated Ocean Research Experiments version 2 (COREv2) data set consists of a globally complete set of air-sea fluxes of momentum, heat and freshwater for 1948-2009 at monthly resolution. This data set serves as a set of common atmospheric boundary conditions that has been used...

"A dataset of historical monthly streamflow at the farthest downstream stations for the world’s 925 largest ocean-reaching rivers has been created for community use. Compared with previous studies, the new dataset has improved homogeneity and enables more reliable assessments of decadal and long-...

TerraClimate is a global gridded dataset of meteorological and water balance variables for 1958-present, available on a monthly timestep. Its relatively fine spatial resolution, global extent, and long length are a unique combination that fills a void in climate data. TerraClimate combines...

Combines observed river discharge information with a climate-driven Water Balance Model in order to develop composite runoff fields that are consistent with observed discharges. This combination preserves the accuracy of discharge measurements as well as the spatial and temporal distribution of...
