摘要
In an embodiment, a system receives first data comprising precipitation gauge measurements at a plurality of gauge locations. The system obtains second data comprising radar based precipitation estimates at the plurality of gauge locations. For each radar based precipitation value at the plurality of gauge locations, the system identifies one or more corresponding precipitation gauge measurement, computes a gauge radar differential value for the radar based precipitation estimate, and stores the gauge radar differential value with location data identifying a corresponding location of the plurality of gauge locations. The system then obtains a particular radar based precipitation estimate at a non-gauge location. The system determines that one or more particular gauge radar differential values at one or more particular gauge locations correspond to the particular radar based precipitation estimate at the non-gauge location and computes a particular radar based precipitation estimate error at the non-gauge location.
