On August 1, the China Meteorological Administration's Beidou sounding project was officially put into operation in Lincang City, Yunnan Province, filling the gap in high-altitude meteorological observation services in the southwestern part of Yunnan.

Yang Heyan, an engineer from the Linxiang District Meteorological Bureau of Lincang City, Yunnan Province, introduced: "The Beidou satellite sounding system is a third-generation sounding system independently developed by my country. It obtains meteorological elements such as temperature, humidity, and air pressure in the three stages of ascent, drift, and descent through Beidou satellite positioning."

According to reports, the project system has high-precision positioning and wind measurement capabilities. By launching a data detector on a weather balloon, the satellite navigation receiver synchronously feeds back the collected information, realizing real-time transmission of Beidou sounding business data and original observation data directly from the station to the national database, breaking through the traditional sounding observation mode.

Ma Zhongliang, deputy director of the Linxiang District Meteorological Bureau of Lincang City, Yunnan Province, said: "The completion of the Lincang Beidou sounding project will greatly improve our tracking and monitoring of small and medium-sized humidity weather systems such as the 'Yunnan-Guizhou quasi-stationary front', 'low (air) shear line' and 'southwest vortex', improve the accuracy of forecasts, and play a practical role in future meteorological disaster prevention and mitigation work."
