Beijing MST (Mesosphere-Stratosphere-Troposphere) Radar is one of the largest facilities within the Chinese Meridian Project, a chain of diverse ground-based remote sensing facilities for monitoring and forecasting the space environment, and is one of only two domestic MST radars. It was built by the Institute of Atmospheric Physics (IAP), Chinese Academy of Sciences (CAS), and is located at the IAP’s Xianghe field observatory in Hebei province (39°45’14.40″N, 116°59’24.00″E). Since July 2011, the Beijing MST radar has been in continuous operation, observing the vertical distribution of winds and turbulence in the troposphere-lower stratosphere and mesosphere-lower thermosphere regions. As one of two MST radars in mainland China, it has produced long-term quality-controlled data for understanding various significant processes and their interaction within and among layers.
