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/negatively correlated with IMF By in the Southern/Northern Hemisphere (SH/NH), respectively, on a day-to-day time scale in most of the 20-summer seasons during the 2007–2017 period with a near 0-day 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 SH but no significant correlation in 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 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 microphysical processes in NLCs, and consequently the ice particle radius and NLC brightness.

Short summary
Both the day-to-day analysis and superposed epoch analysis of the noctilucent cloud (NLC) data revealed conspicuous correlations between NLCs and the solar wind magnetic fields, in both polar regions. The responses in Southern Hemisphere and Northern Hemisphere are opposite and the lag time is fairly short, these two features are beyond the explanations of previous proposed solar photodissociation origin or dynamic origin for the solar-NLC link, and a possible new mechanism is discussed.
