WitrynaIMERG’s gauge calibrated MW precipitation serves as the training reference for RF modeling. In a first step, a recursive backward feature elimination was applied to reduce the number of predictors and to find the best performing feature subset for the classification to improve the performance of the RF model . About 70 predictors are ... Witryna12 mar 2014 · Hence, the similarity in rainfall time series between IMERG and radar estimates confirms a large influence of the Dutch gauge network in the calibration of GPM rainfall retrievals (Fig. 2.3b). It is therefore expected that in places of lower gauge densities the performance of IMERG may not be as good as for the Netherlands.
