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 20230602 and 20230825.
This dataset contains level 1 processed data products version v1.0.1
Data products from this deployment include: rhi, ppi
This version v1.0.1 supersedes the previous version v1.0.0 and includes some additional observations that were not present previously.
For further details of this deployment and the associated dataset please see the internal file metadata.
These data conform to the NCAS data standards and are available under the UK Government Open Licence agreement. Acknowledgement of NCAS as the data provider is required whenever and wherever these data are used.
