Mesoscale and Local Scale Evaluations of Quantitative Precipitation Estimates by Weather Radar Products during a Heavy Rainfall Event

Figure 5

Hourly statistics for radar-derived products and HydraVitis rain gauges ( pixels/rain gauges). (a) Hourly rainfall averaged for 21 pixels (rain gauges) at local scale. Vertical bars indicate the standard deviation (i.e., spatial variability). (b) The mean difference between radar-derived products and rain gauges. (c) Pearson correlation coefficients. The solid grey horizontal lines indicate the value corresponding to statistically significant (Student dist., value = 5%). (d) Nash criterion. Light green triangles and yellow circles, respectively, represent ANTILOPE and PANTHERE products.
