Kriging interpolation methods are often applied without considering measurement
uncertainty, but rarely rain gauge uncertainty is negligible. The most used technique to
consider measurement uncertainty in Kriging is to include a nugget effect in the variogram
model. The nugget is a measurement of the variance that one can expect between two
measurements at short distance. Including a nugget in the variogram model is appropriate
when the uncertainty is stationary in space; if a time-variant variogram is not used, the …
