With the improvement of ground meteorological detection technology and the development of computer data processing technology， the meteorological data documenting advanced greatly， no longer using manual recoding and calculation， and so the auditing emphases are changed to the anaylsis and control of data quality and the rationality of visual measurements. The process of data documenting and auditing of ground meteological observation is described， and some issues， such as the categories， formats and wording of the remarks files， as well as the common errors encountered in maintaining and auditing of ground meteorological observation data files， are discussed in detail， to provide references for observaers to improve the quality of observation data of ground automatic meteorological stations.
