Short summary
Winds in the mesopause region (85–100  km altitude) drive upper-atmospheric dynamics and energy transfer. We present the Asymmetric Spatial Heterodyne Spectrometer, a ground-based instrument, to measure winds by observing the green airglow of atomic oxygen. Lab tests demonstrated the instrument achieves better than 2 m/s accuracy. Field measurements at a high-latitude site in China showed strong agreement with independent LiDAR data, confirming that the system delivers reliable wind retrievals.
