Abstract Based on the automatic observation data and manual observation data of 7 meteorological stations in parallel observation of frozen soil in Xilingol League of Inner Mongolia,this paper makes a comparative analysis of the data of frozen soil observation period,early freezing period,freezing period and melting period.Through analysis,there is a positive correlation between automatic observation data and manual observation data,and the correlation is very significant.The analysis results can provide a theoretical basis for the full automation of frozen soil observation,and also provide a reference for the later algorithm improvement of frozen soil observation instrument.
