Abstract
RHI (range-height indicator) and PPI (plan-position indicator) measurements from the NCAS S-Band CAMRa Weather Radar unit 1 deployed at the NCAS Chilbolton Atmospheric Observatory (CAO). These observations were taken as part of the WesCon - Observing the Evolving Structures of Turbulence (WOEST) project between 20230609 and 20230825.
This dataset contains level 1 processed data products.
Data products from this deployment include: rhi, ppi
