  • Name:  Composite Run Off Fields

  • Description - Composite runoff fields is combined observed river discharge information and climate-driven Water Balance Model. The method applied in the preparation of this data set utilizes a gridded river network at 30-minute spatial resolution to represent the riverine flow pathways and to link the continental land mass to oceans through river channels.   They are consistent with observed discharges and preserve the accuracy of the discharge measurements as well as the spatial and temporal distribution of simulated runoff, thereby providing the "best estimate" of terrestrial runoff over large domains.
