Figure 10: Sensitivity of GMM (with \(M\) = 2) mean (\(\mu\), upper panels) and standard deviation (\(\sigma\), bottom panels) parameters as a function of the precipitation (\(x\)-axis, in mm day\({}^{-1}\)) and according to different PMW detection thresholds of 0. 5, 1.0, 1.5 mm h\({}^{-1}\) (from left to right panels), from the GIRAFE precipitation product. The weight (\(\alpha\)) parameters, for both the M#1 and M#2, are shown in the top right of the figure (upper panels) and represent their respective averages as a function of precipitation.
