Spatial variability in correlation decay distance and influence on angular-distance weighting interpolation of daily precipitation over Europe [PDF]

open access: yes, 2009
Angular-distance weighting (ADW) is a common approach for interpolation of an irregular network of meteorological observations to a regular grid. A widely used version of ADW employs the correlation decay distance (CDD) to (1) select stations that should
