Abstract
Scan data from the National Centre for Atmospheric Science Atmospheric Measurement and Observation Facility's mobile X-band radar unit 2 deployed at Chilbolton Atmospheric Observatory, near Andover, Hampshire, UK from May to September 2023. These observations were taken as part of the (WesCon) experiment - Observing the Evolving Structures of Turbulence (WOEST) project between 20230525 and 20230913.
Data products from this deployment include: volume scans (vol) and vertical cross sections (rhi). The radar performed two sets of volume scans, alternating approximately every 5 minutes, using different parameters for targeting the boundary layer and clouds. Following the volume scans the radar performed a single vertical cross-section. The whole cycle repeated every 10 minutes.
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.
