Abstract & Keywords
Abstract: There are many metal atoms and ions in the mesopause region. These metal atoms can be used as tracers to study the dynamical and chemical processes in this region. Lidar is the most powerful tool for detecting metal atoms and ions. The lidar dataset is of great significance for studying the metal layer in the mesopause region and the coupling between the ionosphere and the middle and upper atmosphere. The lidar dataset is obtained from echo photons detected by sodium lidar and Rayleigh lidar at Meridian Project stations in Beijing, Wuhan, Hefei and Haikou. The dataset includes Rayleigh scattered photon counts from 30 to 80 km, inverse atmosphere density, temperature data, fluorescence scattered photon counts from 80 to 110 km and sodium density data. Through the analysis of the dataset, we can get the response of the metal sodium density to gravity waves and tidal waves in the lower atmosphere, the long-term and short-term variations of the metal sodium layer, the relationship between the sporadic sodium layer and the sporadic E layer; and the density and temperature changes of the middle atmosphere. This dataset also provides more support for the research of space physics.
Keywords: lidar; the metal layer; middle atmosphere density; middle atmosphere temperature
