According to the operation of three new types of radiosondes at the sounding station in Nyingchi from January to April and July in 2020, the most available data are selected, and their performance is evaluated by static and dynamic analysis:(1) from January to April, the percentage of unqualified and replayed instruments arranged from big to small, unqualified: GTS13, GTS11, GTS12, replayed: GTS11, GTS12, GTS13. (2) on the interval between 700 and 250hpa of the ISOBARIC surface layer as defined at 20:00 July, the maximum deviation of the absolute value of the deviation is arranged from large to small, and the temperature is GTS13, GTS11, GTS12. Geopotential height: GTS13, GTS11, GTS12. (3) compared with the standard values of 20:00 radiosonde second data elements of the new instrument in a single day, the absolute values of the deviation range from large to small in order, temperature ≤0.50 °C: Gts13, Gts11, GTS12; humidity ≤5% : GTS13, GTS11, GTS12.
