- NEW METHOD OF INTERPOLATION 1.Horizontal-distance and direction influences (based on modified Shepards interpolator) 2. Additional topographic influences on interpolated precipitation (from elevation, slope, slope orientation and the degree of exposure to orography Important: the orographic scale Orographic elevation Longitudinal and latitudinal components of the slope of the orographic region Potential exposure of station i to orography We can estimate an interpolation bias for each station (when topographic influences Are not taken into account): from nearby stations Pi ( Then we can estimate And finally:
