Abstract:Taking the example of Xilinhaote and Nanjing sounding stations,this paper makesa comparison for geopotential height calculated by radar location,pressure calculation and GPS radiosonde respectively.Meanwhile,the pressure values measured bythe radar,GTS1 pressure sensor and GPS wind sounder are compared.The results show that the geopotential height can be calculated by radar location instead of pressure calculation.With the substitution of radiosonde direct measurement,the pressure above 40 hPa can be anti-calculated based on radar height.In the case ofusing L-band radar,the feasibility of pressure anti-calculated by means of the height should be studied further.
