Abstract
In recent years, the interest in natural resources management is increased. In this context, control charts, developed to monitor and maintain quality in industrial processes, are a useful moni- toring and decision tool. In this paper, the behavior of an agro-metereological variable, named evapotranspiration, in an area of the northern part of Italy during a 25-year span (from 1992 to 2016) is studied through a nonpara- metric spatio-temporal geostatistical analysis and multiple CUSUM control charts. In particular, the probability that the variable registers an “out of control” is estimated for three decades period from the 10th to the 30th of January 2017.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
