The Raikoke volcano erupted on 21–22 June 2019 and emitted large amounts of volcanic
ash into the upper troposphere, and later might impose long-term effects on the global and
regional radiation budget after the long-range transport of volcanic aerosol plumes. Height-
resolved ground-based lidar observations are beneficial to trace and cross-check the 3-D
evolution of complicated aerosol plumes, which are, however, scarce at mid-latitude regions.

The Raikoke volcano erupted on 21-22 June 2019 and emitted~ 1.5 Tg volcanic ash into the
atmosphere. Several previous studies have focused on the large-scale dispersion of
volcanic aerosol plumes with space-borne observations and dispersion models. However,
height-resolved ground-based observations are still necessary to trace and cross-check the
3-D evolution of aerosol plumes due to their complicated structures. Here, we present a rare
ground-based lidar observation of Raikoke aerosol plumes in the mid-latitudes of the …
