River network based characterization of errors in remotely sensed rainfall products in hydrological applications
The authors propose a hydrologic evaluation framework for gridded rainfall products. This framework makes use of the Spatial Stream Network (SSN) statistical method to provide spatial characterization of the discrepancies between two gridded rainfall products. The SSN method relies on using stream network length rather than the traditionally used Euclidean distances.It also accounts for the flow connectivity information between the network segments.
