“…Such periods are characteristic of internal gravity waves and are their manifestation in the ionosphere and the neutral atmosphere parameters. The results of long-term measurements of the parameters of the neutral component and the plasma vertical velocity in the lower ionosphere by the API technique convincingly demonstrate a significant effect of atmospheric waves, which are most intense during natural disturbances [16,17,33]. The amplitude of the waves can reach 50-100 K in…”

“…In the lower ionosphere T e0 = T i0 = T, where T is the neutral temperature. The given expression for τ underlies the determination of most of the parameters of the lower ionosphere [8,16,18,[24][25][26]. Temporal density variations repeat in general temperature variations.…”

“…Lidar observation, airglow imaging, measurements of the horizontal wind by meteor radar, and satellite observation allow one to determine IGW vertical and horizontal parameters from the lower atmosphere to the thermosphere [11][12][13][14][15]. Among these techniques, the method based on a scattering of high frequency radio waves by artificial periodic irregularities of the ionospheric plasma is promising [8,[16][17][18][19][20][21][22][23].…”

We present results of the studies of internal gravity waves based on altitude-time dependences of the temperature and the density of the neutral component and the velocity of the vertical plasma motion at altitudes of the lower ionosphere (60–130 km). The vertical plasma velocity, which in the specified altitude range is equal to the velocity of the neutral component, the temperature, and the density of the neutral atmosphere are determined by the method of the resonant scattering of radio waves by artificial periodic irregularities (APIs) of the ionosphere plasma. We have developed an API technique and now we are evolving it for studying the ionosphere and the neutral atmosphere using the Sura heating facility (56.1 N; 46.1 E), Nizhny Novgorod, Russia. An advantage of the API technique is the opportunity to determine the parameters of the undisturbed natural environment under a disturbance of the ionosphere by a field of powerful high frequency radio waves. Analysis of altitude-time variations of the neutral temperature, the density, and the vertical plasma velocity allows one to estimate periods of atmospheric waves propagation. Wavelike variations with a period from 5 min to 3 h and more are clearly determined.

“…The atmospheric temperature and density are determined from the API relaxation time, which is inversely proportional to the ambipolar diffusion coefficient. Many results of studying the altitude-temporal variations of temperature and density in different geo-and helio-physical conditions are presented in Reference [23][24][25][26][27][28].…”

Study of a Gas Disturbance Mode Content Based on the Measurement of Atmospheric Parameters at the Heights of the Mesosphere and Lower Thermosphere

The main result of this work is the estimation of the entropy mode accompanying a wave disturbance, observed at the atmosphere heights range of 90–120 km. The study is the direct continuation and development of recent results on diagnosis of the acoustic wave with the separation on direction of propagation. The estimation of the entropy mode contribution relies upon the measurements of the three dynamic variables (the temperature, density, and vertical velocity perturbations) of the neutral atmosphere measured by the method of the resonant scattering of radio waves on the artificial periodic irregularities of the ionospheric plasma. The measurement of the atmosphere dynamic parameters was carried out on the SURA heating facility. The mathematical foundation of the mode separation algorithm is based on the dynamic projection operators technique. The operators are constructed via the eigenvectors of the coordinate evolution operator of the transformed system of balance equations of the hydro-thermodynamics.
