The rainfall observation data of 2590 hours from the Parsivel laser disdrometers, tipping bucket rain gauges, and weighing rain gauges of Nanjing Meteorological Service in Jiangning Station during 2014-2018 are collected, and the performance of the Parsivel laser disdrometer for rainfall and snowfall measurement is discussed. The results show that compared with the results of the weighing rain gauge, both rainfall duration and total accumulated rainfall measured by the tipping rain gauge are lower, while the rainfall duration measured by the laser disdrometer is lower, but the total accumulated rainfall is 15.07% higher. The laser disdrometer can track the change of rain intensity effectively, but the rain intensity tends to be underestimated when the rain is light (<2.5 mm h-1), and overestimated for different degrees when the rain is heavy (≥2.5 mmm h-1). 〖JP2〗The tipping bucket rain gauge is unable to measure snowfall effectively, while the laser disdrometer can monitor the change of snowfall effectively, but it overestimates the equivalent precipitation intensity due to its limitation of measurement principle.The performance of laser disdrometer did not deteriorate with the increase of installation time from the data of 5 years.〖JP〗
