[PDF][PDF] Integration of rain gauge errors in radar-rain gauge merging techniques
F Cecinati, AM Moreno Ródenas… - Proceedings of the 10th …, 2017 - ewra.net
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 …
