Outline
To achieve high-precision, routine networked detection of neutral wind fields in the middle and upper atmosphere, relying on Phase II of the Chinese Meridian Project, we have overcome challenges including large-field-of-view, high-throughput and ultra-high-resolution optical design, decoupling of multispectral interference aliasing, large-size cavity thermal stabilization (±0.003 K precision), and real-time thermal drift calibration. A ground-based passive optical instrument, the Dual-Channel Optical Interferometer based on Asymmetric Spatial Heterodyne Spectroscopy (ASHS), has been independently developed. The world’s first running ASHS atmospheric wind field observation network has been established, enabling coordinated observations of wind fields at the mesopause and thermosphere. Cross-comparisons with independent observations such as meteor radars and lidars yield statistical correlation coefficients ranging from 0.75 to 0.95, showing good consistency in day-to-day variations and mutually validating the accuracy and reliability of neutral wind measurements. This detection network fills the gap in large-scale, long-term continuous wind-field monitoring over East Asia, effectively supporting research on middle and upper atmospheric dynamical evolution and geomagnetic storm responses. The research outcomes have realized the engineering application of ASHS wind measurement technique and established an efficient and stable ground-based optical wind-field observation system, providing a technical foundation for establishing a ground-space integrated three-dimensional wind field detection system and future space weather exploration programs.
