“…In addition, raindrops in DSDs with unmatched D ‐ V (normal D / V vs. excessively large or small V / D ) were also considered to be unreliable data, which could be produced under strong wind shear conditions or by raindrops splashing on the surface of the instrument. We compared the measured D ‐ V of OTT data with the Atlas diameter‐velocity empirical model (Atlas et al.,
1973), and data with more than 50% deviation between theoretical and measured velocity were removed by quality control (Liu et al.,
2023):
In this experiment, the OTT data from July to November 2021 are used to calibrate the γ rain ‐ R relationship. The fitted γ rain ‐ R relationship and ITU‐R model are shown in Figure 5.…”
