The relationship between AGW and travelling ionospheric disturbances (TIDs) in the atmosphere was investigated in measurements of particle concentration, temperature, and velocity. Methods of processing satellite data for recording wave disturbances in the atmosphere have been improved. Quantitative and qualitative characteristics of the response of the ionosphere to the propagation of atmospheric gravity waves over the Antarctic were obtained based on satellite measurements. The ratio of the amplitudes of AGW and TID in different spatial regions was analyzed. The mechanisms of spectrum filtering and changes in wave amplitudes during propagation in non-uniform wind flows were studied. Product Description popup.authors Vlasov Dmytro I.
