WOEST: Scan and vertically pointing data from the NCAS Ka-Band Mobile Cloud Radar unit 1 deployed at MOD Lyneham, v1.0.0 (20230524-20230906)
Abstract
RHI (range-height indicator) and PPI (plan-position indicator) scan measurements from the NCAS Ka-Band Mobile Cloud Radar 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 20230524 and 20230906.
Data products from this deployment are grouped into two sets.
Intensive observing period (IOP) data include RHI (range-height indicator) scans providing vertical cross-sections through individual storm cells.
Standard observing period (SOP) data include a repeating sequence of (a) VPT – a vertically pointing dwell for 18 minutes; (b) VAD – a conical scan at an elevation 8° from zenith with the aim of measuring a vertical wind profile; (c) HSRHI – a sequence of of twelve horizon-to-horizon scans in elevation spaced by 30° in azimuth; and (d) BLPPI – a sequence of conical scans at a set of low elevations. The full SOP sequence was repeated every 30 minutes.
VPT data are grouped into daily files and include measurements from additional vertical dwells during IOPs.
