Plasma and neutral gas variations registered onboard Dynamics Explorer 2 satellite by NACS-instrument (Neutral Atmosphere Composition Spectrometer, detector of the neutral species densities) and RPA-instrument (Retarding Potential Analyzer, detector of the ion density and temperature). Measurement data are filtered in bandwidth 100–1000 km. There are shown (from top to bottom) relative perturbations in neutral density δρ/ρ, ion temperature δT/T, ion concentration δn i /n i , atomic oxygen δ[O]/[O] and molecular nitrogen δ[N2]/[N2] concentrations. Counts are binding to time, altitude, and geographical coordinates of the satellite. AGW waveform is clearly distinguishable in neutral gas parameters. Variations of plasma parameters are noisier being partly caused by AGW, partly by different causes.
