This dataset is a curated collection of VHF radar echo intensity and Doppler data observed by the Sanya Observatory. It includes parameters such as line-of-sight distance, signal strength, signal power, average Doppler velocity, and Doppler spectral width. As a multi-level, multi-parameter ground-based observation dataset for China's regional space environment, it plays a critical role in basic research fields including space physics and geophysics, as well as applications such as national defense and satellite navigation and positioning. It can be applied to studies on the characteristics and variations of regions including China's ionosphere, middle and upper atmosphere, and geomagnetism; investigations into the coupling and dynamic processes of Earth's various spheres; analyses of the response of Earth's space environment to solar activity; real-time monitoring and forecasting of space weather; the development of empirical models for relevant parameters; and ionospheric radio wave correction for satellite positioning and navigation, among other related research topics.
