Aiming at the problem that the measurement results of OTT-Parsivel in elevated environment are prone to error due to the influence of ambient air flow, the authors propose the detection test of OTT-Parsivel on unstable platform, proposes the quality control method under different levels of wind speed, gives the measurement speed correction model, and gives simulation and error analysis. Based on the summer precipitation process in Beijing in 2020, several precipitation cases are analyzed by using the measured data of OTT-Parsivel, three-dimensional ultrasonic wind thermometer and dynamic inclination sensor at 280 meters. The results show that the proposed model has a good correction effect on the vertical falling velocity of raindrops, the velocity distribution of each dimension tends to be normal distribution, and the number of effective particles can increased by 6%. When the horizontal wind speed exceeds 8 m/s, the availability of OTT-Parsivel raindrop spectrometer measurement data is improved.
