“…STEREO (Cyr et al, 2009). Szalay et al (2020) also noted that such secondary particles were observed with the WISPR experiment on PSP (see e.g. Vourlidas et al, 2016) and that the ejecta correlated well with antenna measurements of dust impacts.…”

“…Based on recent observations by the Parker Solar Probe (PSP), Szalay et al (2020) concluded that β meteoroids (β describing the ratio of the radiation pressure force to gravity) dominate the recorded dust flux. They found that such grains typically have larger impact velocities than circularly bounded dust, but for β 0.5, there may be a non-vanishing flux of β meteoroids with impact speeds in the upper limit of the velocity range investigated in the present work for contact charging.…”

A comparison of contact charging and impact ionization in low-velocity impacts: implications for dust detection in space

Abstract. We investigate the generation of charge due to collision between projectiles with sizes below ∼1 µm and metal surfaces at speeds ∼0.1 to 10 km s−1. This corresponds to speeds above the elastic limit and well below speeds where volume ionization can occur. Impact charge production at these low to intermediate speeds has traditionally been described by invoking the theory of shock wave ionization. By looking at the thermodynamics of the low-velocity solution of shock wave ionization, we find that such a mechanism alone is not sufficient to account for the recorded charge production in a number of scenarios in the laboratory and in space. We propose a model of capacitive contact charging that involves no direct ionization, in which we allow for projectile fragmentation upon impact. Furthermore, we show that this model describes measurements of metal–metal impacts in the laboratory well. We also address contact charging in the context of ice-on-metal collisions and apply our results to rocket observations of mesospheric dust. In general, we find that contact charging dominates at speeds of up to a few kilometres per second and complements shock wave ionization up to speeds where direct ionization can take place. The conditions that we consider can be applied to dust particles naturally occurring in space and in Earth's upper atmosphere and their direct impacts on rockets, spacecraft, and impacts of secondary ejecta.

“…Note that the NLCs are absent in the winter hemisphere, whereas polar mesosphere winter echoes (PMWEs) were still observed at much lower al-titudes of 55-85 km. PMWEs are suggested to be caused by the neutral air turbulence together with the charged MSPs (Strelnikov et al, 2021). A possible link is expected to exist between PMSEs and PMWEs with IMF B y for two reasons: first, the PMSE is sensitive to ice particle radius and concentration, due to the fact that ice particles can affect the diffusion of electrons (Rapp and Lübken, 2004).…”

Responses of CIPS/AIM noctilucent clouds to the interplanetary magnetic field

Abstract. This study investigates the link between the interplanetary magnetic field (IMF) By component and the noctilucent clouds (NLCs) measured by the Cloud Imaging and Particle Size (CIPS) experiment onboard the Aeronomy of Ice in the Mesosphere (AIM) satellite. The mean ice particle radius in NLCs is found to be positively correlated with IMF By in the Southern Hemisphere (SH) and negatively correlated with IMF By in the Northern Hemisphere (NH), respectively, on a day-to-day timescale in most of the 20 summer seasons during the 2007–2017 period with a near 0 d lag time, and the response in the SH is stronger than that in the NH. Moreover, the albedo, ice water content and frequency of occurrence of NLCs present positive correlation with IMF By in the SH but no significant correlation in the NH. The superposed epoch analysis (SEA) further indicates the rm on average changes by about 0.73 nm after IMF By reversals, which is significant at the 90 % confidence level in Monte Carlo sensitivity tests. Our results suggest an IMF By-driven pathway: the influence of the solar wind on the polar ionospheric electric potential affects the nucleation processes in NLCs and consequently the ice particle radius and NLC brightness.

“…Radar observations, which are not constrained by tropospheric weather conditions (unlike lidar), have enabled long-term trend measurements of PMSE and hence NLCs (Latteck et al, 2021). A related topic of current research is polar mesosphere winter echoes (PMWE) and their relationship to atmospheric turbulence and possibly MSPs (Strelnikov et al, 2021).…”

Abstract. This Opinion article begins with a review of important advances in the science of the Mesosphere and Lower Thermosphere (MLT) region of the atmosphere that have occurred over the past two decades since the founding of Atmospheric Chemistry and Physics. The emphasis is on chemistry (although, of course, this cannot be decoupled from discussion of atmospheric physics and dynamics), and the primary focus is on work during the past 10 years. Topics that are covered include: observations (satellite, rocket and ground-based techniques); the variability and connectedness of the MLT on various length- and time-scales; airglow emissions; the cosmic dust input and meteoric metal layers; and noctilucent (or polar mesospheric) ice clouds. The paper then concludes with a discussion of important unanswered questions and likely future directions for the field over the next decade.
