Abstract
Aerosol backscatter measurements from the National Centre for Atmospheric Science (NCAS) Lidar Ceilometer unit 1 deployed at MOD Lyneham. These observations were taken as part of the Wessex convection (WesCon) experiment - Observing the Evolving Structures of Turbulence (WOEST) between 20230523 and 20230911.
Data products from this deployment include: aerosol-backscatter
