Abstract Using the comparative observation data obtained during the conversion of the upper-air sounding station instruments to parallel observation in Xingtai,the average difference of geopotential height and temperature among GTS13 digital sounder,GTS12 digital sounder and GTS1 current digital sounder is analyzed by means of chart.The results show that the GTS13 digital sounder has no obvious systematic difference in altitude below 100hPa,while GTS12 digital sounder has no obvious systematic difference in altitude below 400hPa.But the system difference between the two new types of sounder at 20:00 is less than that at 08:00.It is shown that the difference between the systems is directly related to the observation time.Due to the different manufacturers,the different raw materials and production techniques of sounder also result in the difference of observation data.

Key words： L-band radar upper-air sounding comparative analysis difference
