Item Metadata only Comparing Areal Rainfall Estimation Methods in the Ayung Watershed, Bali, Indonesia: A Comprehensive Analysis(2024-01-01) Dharmayasa I.G.N.P.; Putri P.I.D.; Sugiana I.P.; Jindal R.; Surakit K.; Thongdara R.; Dharmayasa I.G.N.P.; Mahidol University, and infrastructure design. Three methods are evaluated: arithmetic average, Thiessen polygon, and Inverse Distance Weighting (IDW). Rainfall data from eight stations across the watershed (2004-2018) reveals a distinct wet-dry season pattern. All three methods yielded... consistent results for areal rainfall estimation, with IDW showing a slight advantage in accuracy. However, the arithmetic average method offers a simpler and faster computational approach, making it suitable for initial analyses. Spatial interpolationPublication Metadata only A comparison of spatial interpolation methods for surface temperature in Thailand(2013-12-01) Panudda Tiengrod; Waranyu Wongseree; Mahidol University. Inverse distance weighting (IDW) and ordinary kriging (OK) were used to interpolate surface temperature. Leave-one-out cross-validation (LOOCV) had been use to analyze the spatial error of interpolated data. The result of a Wilcoxon signed rank test
