1. A computer-implemented method for validating data delivered by a rain gauge, the method comprising steps of:
receiving, in a defined time window, pluviometric data from a gauge and weather data from at least one weather radar;
computing a coefficient of gauge/radar similarity between the pluviometric data received from said gauge and the weather data received from said at least one weather radar;
comparing the value of the coefficient of obtained gauge/radar similarity to a threshold gauge/radar value; and
validating the pluviometric data of said gauge if the value of the coefficient of gauge/radar similarity is higher than or equal to the threshold gauge/radar value; or
if the coefficient of gauge/radar similarity is lower than the threshold gauge/radar value:
identifying, in a given geographic region, a set of neighboring gauges of said gauge;
determining, among the neighboring gauges, those belonging to the same rain cell as said gauge, a rain cell containing gauges the weather data of which, as received from said at least one radar, at the positions of these gauges are similar over said time window;
computing a coefficient of gauge/gauge similarity between the pluviometric data of said gauge and the pluviometric data of each of the neighboring gauges belonging to the same rain cell;
collating the results of the computations of the coefficient of gauge/gauge similarity to obtain a coefficient-of-gauge/gauge-similarity value;
comparing the obtained value of the coefficient of gauge/gauge similarity to a threshold gauge/gauge value; and
validating the pluviometric data of said gauge if the value of the coefficient of gauge/gauge similarity is higher than or equal to the threshold gauge/gauge value.
