    • Abstract
  • The method to identify the tropopause height directly from the bending angle profile of global positioning system(GPS) radio occultation(RO) is studied.Using the GPS RO observations provided by the Constellation Observing System for Meteorology,Ionosphere and Climate(COSMIC) mission,the heights of the tropopause are identified directly from the RO bending angle profiles.These tropopause heights are compared with the cold point tropopause(CPT) and the lapse rate tropopause(LRT) determined from the temperature profiles of the corresponding RO events,as well as the CPT and the LRT derived from the radiosonde observations occur within 300 km and 3 hours of the RO events.The results show that to identify the tropopause directly from the bending angle profiles of GPS RO observations is feasible.
