Comparison study of wind profile and tropopause height estimated by Wuhan atmosphere radio exploration radar and GPS radiosonde

The Wuhan atmosphere radio exploration (WARE) radar is one of the significant facilities of the Meridian Space Weather Monitoring Project of China and dedicated to real-time atmospheric observations. We compare the Wuhan MST radar wind data (3-25 km) with the simultaneous radiosonde data and the temperature data computed from NRLMSISE00 models. Our results show good agreement between the wind field data from Wuhan MST radar and from the GPS radiosonde. The tropopause heights determined by the three methods are close to each other. In terms of the structure constant of atmospheric refractive index Wuhan MST radar gives a height of 15-16.5 km, the GPS radiosonde temperature profile reads that of 16.5-17 km, and NRLMSISE00 modeling computes a value of 16.2 km. Current work indicates that the WAER radar is operative and its data are reliable.
