Mesospheric plasma irregularities caused by the missile destruction on 9 December 2009
Abstract On 9 December 2009 at about 07 UT a solid propellant 36.8 t ballistic rocket was self‐destroyed at an altitude of 170–260 km, at a distance of about 500 km to the east of Sodankylä Geophysical Observatory (SGO, 67°22′N, 26°38′E, Finland). After 2–3 h the SGO meteor radar (operating at a fre...

The turbulence occurred at a height of about 80 km and was localized in several areas of about 60 km in horizontal scale. Line‐of‐sight velocity of the irregularities was up to a few tens of meters per second toward the radar.

Aerosol particles caused by the missile explosion played a key role in producing the electron density irregularities. As a possible explanation, we suggest that sedimented by gravity and, hence, moving with respect to the air, charged aerosol particles (presumably composed of aluminum oxide) might produce meter‐scale irregularities (electrostatic waves) via dissipative instability, which is a mechanism analogous to that of the resistive beam‐plasma instability.
