Abstract: The near-space region is a crucial airspace domain, but due to the scarcity of tracers and difficulties in acquiring observational data, existing measurements are extremely limited. A medium-frequency (MF) radar system operated by the Yunnan Kunming Electromagnetic Environment National Observation and Research Station (25.6°N, 103.7°E) of the China Research Institute of Radiowave Propagation serves as an instrument for detecting the near space region and lower ionosphere. This radar receives partial reflection echoes from lower ionospheric plasma irregularities, employing both Full Correlation Analysis (FCA) and Differential Absorption Experiment (DAE) methods to retrieve atmospheric horizontal wind fields and electron density information at 60–100 km altitudes, with both FCA and DAE data formats being stored. Based on this MF radar dataset, researchers can conduct studies on atmospheric wind field characteristics in near-space and electron density variations in the lower ionosphere over Southwest China (above Kunming station), exploring coupling effects and physical mechanisms between the neutral atmosphere and ionosphere. This dataset also supports high-precision ionospheric numerical prediction models, serving ionospheric communication assurance requirements.
