To use precipitation data more effectively,this paper analyzed the performance of DSC2 weighing gauge in precipitation observation.We selected the precipitation observation data from 13 national meteorological stations in Beijing from April to October 2013 to do research.The data were collected by weighing gauge,manual way and tipping gauge,respectively.The analysis was focused on the differences of total rainfall and daily precipitation observed by the three ways.The results showed that,among the samples,the errors of total precipitation from 12 stations are in line with the requirement of current operation and the grade judgment of daily precipitation by the three ways are basically consistent.Comparing the weighting gauge with manual way,the daily mean precipitation by weighing gauge shows a 0.13 mm less,and the daily precipitation correlation coefficient is 0.9968.The observation result by weighing gauge is averagely 0.17 mm less than the result by tipping gauge and the correlation coefficient is 0.9983.
