Comment on “Stratospheric Aerosol Composition Observed by the
Atmospheric Chemistry Experiment Following the 2019 Raikoke Eruption’ by
Boone et al.
This is a comment on the Boone et al. (2022) article. The authors
analyzed spaceborne observations of stratospheric aerosol in 2019-2020 .
They concluded, the dominating aerosol type was volcanic sulfate
aerosol. They critisized Raman lidar observations of Ohneiser et al.
(2021) and Ansmann et al. (2021). These authors classified the aerosol
as wildfire smoke. Boone et al. (2022) stated that this classification
is wrong. In this article, we clearly show that the dominant aerosol
type was wildfire smoke.
