 This research compared the performance of several geostatistical and deterministic methods for daily rainfall interpolation. The authors found that the best method for daily rainfall interpolation was ordinary cryging, ORK, followed by uncertainty neighborhood cryging, UNK, and cryging with external drift, KD. They also noted that the use of multiple variegrams improved the performance of the deterministic methods, while the use of external drift improved the performance of the geostatistical methods.
