“…Embedded inside the V‐shape enhancement region are the rTEC depletions, and they are previously known to be formed mainly by the neutral molecule of rocket exhaust plumes (i.e., water and ice particles) that rapidly decrease the ionospheric plasma through the much faster dissociative recombination processes [cf. Karlov et al ., ; Platov and Kosch , ; Mendillo et al , ; Furuya and Heki , ]. More than 10 min after rocket passage, there are delayed disturbance waves propagating outward from the east side of the V‐shape structure (denoted by red dashed curves in Figures d–e).…”

Observations and theoretical modeling of the ionospheric disturbance waves generated by rocket launches are investigated. During the rocket passage, time rate change of total electron content (rTEC) enhancement with the V‐shape shock wave signature is commonly observed, followed by acoustic wave disturbances and region of negative rTEC centered along the trajectory. Ten to fifteen min after the rocket passage, delayed disturbance waves appeared and propagated along direction normal to the V‐shape wavefronts. These observation features appeared most prominently in the 2016 North Korea rocket launch showing a very distinct V‐shape rTEC enhancement over enormous areas along the southeast flight trajectory despite that it was also appeared in the 2009 North Korea rocket launch with the eastward flight trajectory. Numerical simulations using the physical‐based nonlinear and nonhydrostatic coupled model of neutral atmosphere and ionosphere reproduce promised results in qualitative agreement with the characteristics of ionospheric disturbance waves observed in the 2009 event by considering the released energy of the rocket exhaust as the disturbance source. Simulations reproduce the shock wave signature of electron density enhancement, acoustic wave disturbances, the electron density depletion due to the rocket‐induced pressure bulge, and the delayed disturbance waves. The pressure bulge results in outward neutral wind flows carrying neutrals and plasma away from it and leading to electron density depletions. Simulations further show, for the first time, that the delayed disturbance waves are produced by the surface reflection of the earlier arrival acoustic wave disturbances.

“…Platov and Kosch [] comprehensively considered the thermal balance of ice particles in the upper atmosphere and demonstrated that the sublimation time of ice particles explains the formation of a large‐scale gas‐dust cloud around the rocket trajectory at radial distances up to 200–300 km.

[1] Detailed tracing of an exhaust plume from a rocket's initial trajectory is a scientifically and diagnostically useful technique. It can provide detailed information on the atmosphere's mean winds, wind shears, turbulent regime, and physical state over a wide altitude range from 50 to 200 km. We analyze Soyuz rocket exhaust plumes from Plesetsk on 21 May 2009 and 27 June 2011, which uncovered significantly different atmospheric states and underlying dynamics. The first case showed highly dynamical conditions in the mesosphere, characterized by vortex structures, wind shears, and small-scale turbulent eddies. The estimated turbulent energy dissipation rates ranged 330-460 mW kg À1. A characteristic balloon-shaped trail was observed at altitudes between 105 and 160 km, having rapid expansion rates of 500-800 m s À1 over the time period of 2 min which can be explained by complex gas dynamic processes in the rocket wake involving the collision of shock waves. In the second case, we show evidence that the rocket exhaust trail persisted without any changes during its motion from Plesetsk via Denmark to the UK for 9 h, indicating extremely stable atmospheric conditions. This case introduces a new state of the summer mesosphere-remarkably quiet conditions, probably never observed before. The rocket plumes studied, related to the initial rocket trajectory, are essentially twilight phenomena as seen from the ground using wideband spectrum cameras, that is, the Sun should be below the horizon by 6°. For the first time, we analyze the dynamics of rocket exhaust products at the initial trajectory in the mesosphere and lower thermosphere using detailed photographic imaging taken from the ground.Citation: Dalin, P., et al.

“…12 Optical phenomena associated with gas formations containing ice particles have been observed at high altitudes. 3,13 Reference 3 suggests that similar optical phenomena might develop also at lower altitudes ∼150 km, but could be hidden by the luminosity of twilight or other brighter optical formations. We suggest that if a dusty plasma instability can occur, perhaps radar backscattering from the unstable waves might be a diagnostic of such artificial ice particles clouds at lower altitudes.…”

“…We suggest that radar backscatter from such unstable waves, which propagate perpendicular to the magnetic field, might have application as a diagnostic for lower-altitude ice/dust-gas formations arising from rocket exhaust. 3,13 We note, however, that we have used sets of nominal background plasma parameters and possible dust parameters. Further work should include more detailed evaluations involving ranges of gas, dust, and plasma parameters that might occur in such rocket exhaust clouds at different altitudes.…”
