Short summary
This paper documents the evolution of the cloud of volcanic aerosol introduced into the stratosphere by the eruption of Raikoke in June 2019. The measurements were made by a UV lidar (laser radar) operated at Capel Dewi, Wales, between June 2019 and May 2020. They show how the cloud of volcanic aerosol arrived at the site and how its optical depth decreased by a factor of 5 over the 11 months of measurements.
