Polarization Analysis and Probable Origin of Bright Noctilucent Clouds with Large Particles in June 2018
arXiv:1808.01475 · doi:10.1016/j.pss.2019.104713
Abstract
A sequence of very bright noctilucent clouds (NLC) was observed in central Russia during the last decade of June, 2018. It followed the meteorite impact 300 km southwards from Moscow in the morning of June 21. Polarization measurements of NLC in a wide range of scattering angles allowed finding the effective size of ice particles forming the clouds. These estimations together with satellite data on gravity waves, temperature, and water vapor mixing ratio during these days help to understand the basic causes of the observed NLC brightness and particle size anomaly.
