Short summary
This study evaluates the reliability of precipitation measurements from disdrometers under different wet-bulb temperatures. Using four years of 2DVD (Two-dimensional Video Disdrometer) data compared with tipping-bucket and weighing rain gauges, three quality control methods based on fall velocity showed high reliability (correlation > 0.98) when Tw exceeded 5 °C. However, accuracy declined sharply when Tw was below 2 °C, with correlation dropping below 0.6.
