Objective Using COSMIC occultation data in 2011,the atmospheric temperature profiles in Antarcticaare inversed,and the tropopause parameters(temperature and altitude)are extracted.The spatial andtemporal Antarctic tropopause variations are analyzed quantitatively.In Antarctica,the temperaturelapse rate tropopause is more accurate than the coldest point tropopause,and the occultation method isthe same as ozonesonde and radiosonde.The Antarctic tropopause shows one wave structure with con-trary phase,temperature ranges from 200Kto 230K,the height from 9km to 11km.Antarctic trop-opause disappears in winter and spring,and occurs inversion layer in summer and autumn.The tropo-pause temperature in winter and spring shows significant gradient feature.In latitude direction,thetemperature is low near the pole,high around;in longitude direction,the temperature is lower in theWest Antarctica.
