Abstract Using the observation data of DSG5 precipitation instrument and manual observation records from August 2017 to January 2018 at Dongsheng station,the DSG5 phenomenon instrument is evaluated and analyzed.The results show that the capture rate of precipitation instrument is higher and the false alarm rate is 5.7%.The main difference is that the records of precipitation phenomena are not consistent with the records of manual observation for the drizzle.And the precipitation coincidence rate is 71%.It is recommended to cooperate with auxiliary equipment such as cameras to improve the quality of manual observation,guaranteeing the accuracy of reference standard values (manual observation records).After intensive observations on typical precipitation process or extended parallel observation time,the evaluation and analysis will be continued.
