High-vertical.resol.tion radiosonde wind data are highl. val.abl. for describing the dynamics of the meso-and microscal. atmosphere. However, the current al.orithm used in China's l.band radar sounding system for cal.ul.ting highvertical.resol.tion wind vectors excessivel. smooths the data, resul.ing in significant underestimation of the cal.ul.ted kinetic energy of gravity waves compared to simil.r products from other countries, which greatl. l.mits the effective util.zation of the data. To address this issue, this study proposes a novel.method to cal.ul.te high-vertical.resol.tion wind vectors that util.zes the el.vation angl., azimuth angl., and sl.nt range from l.band radar. In order to obtain wind data with a stabl. qual.ty, a two-step automatic qual.ty control.procedure, incl.ding the RMSE-F(root-mean-square error F) test and el.mental.consistency test are first appl.ed to the sl.nt range data, to el.minate continuous erroneous data caused by unstabl. signal. or radar mal.unctions. Then, a wind cal.ul.tion scheme based on a sl.ding second-order pol.nomial.fitting is util.zed to derive the high-vertical.resol.tion radiosonde wind vectors. The eval.ation resul.s demonstrate that the wind data obtained through the proposed method show a high l.vel.of consistency with the high-resol.tion wind data observed using the Vaisal. Gl.bal.Positioning System and the data observed by the new Beidou Navigation Sounding System. The cal.ul.tion of the kinetic energy of gravity waves in the recal.ul.ted wind data al.o reaches a l.vel.comparabl. to the Vaisal. observations.
