Identifying Individual Rain Events with a Dense Disdrometer Network

Figure 8

One-minute drop spectra for the interval discussed in Figure 6. The -axis displays elapsed time through the subinterval in hours; the -axis indicates the size bin of the associated drops. Color indicates the number of drops measured in the associated time interval (red corresponds to high concentrations; blue corresponds to low). The spectra for detectors A and B are shown, which—when analyzed in Figure 6—saw different numbers of events. Given the striking similarity of the underlying data, it seems reasonable to conclude that the spurious “tip” in detector B that prevented two separate events from being identified as one event was likely due to chance.
