Abstract：Based on the meteorological observation data of Jinnan national meteorological observation station from 1974 to 2013,this paper analyzes the integrity,regional consistency and uniformity of the observed data sequence through the statistics of the missing measurement rate and the distribution of the missing measurement years.It is concluded that the data of average temperature,maximum temperature,minimum temperature,precipitation,average relative humidity and average wind speed (2 min) observed by Jinnan national meteorological observation station since its establishment are relatively complete.And the trend change characteristics are basically the same year by year,without obvious difference.The change of station,instrument and operation of automatic station have some effects on the uniformity of observation data in Jinnan national meteorological observation station.
