WesCon: Met Office surface to 16 m meteorology, radiation and subsoil measurements from Airfield Camp, Netheravon, v1.0 (20230421-20230914)

A continuous hydrometeorological record of the temporary Met Office Observation-based research site at Netheravon, Wiltshire (51.241°N, -1.777°W, 120 m amsl) in southern England during the summer of 2023. Netheravon formed a supersite for the Wessex Summertime Convection Experiment (WesCon)/WesCon - Observing the Evolving Structures of Turbulence (WOEST) field campaign. This dataset contains recorded surface meteorology, radiation and subsoil measurements from sensors mounted on a combination of 1.2 m, 2 m and 16 m masts at 1, 5, 10, and 30 minute averaging periods.

Instruments mounted on 1.2m, 2 m and 16 m masts include:
• Vector Instruments T302 PRT temperature sensors.
• Screened and aspirated HMP155s for measuring temperature and relative humidity.
• Gill HS50 3-D horizontally symmetric ultrasonic anemometers for winds and turbulent heat fluxes.
• Licor Li-7500 high-speed open-path hygrometer was located at 16 m.
• Delta-T BS5 measured barometric pressure at 1.5 m.

Surface instrumentation includes:
• Rainfall is measured with a EML SB500 tipping-bucket gauge with a 0.2 mm accuracy.
• Screened and aspirated Rotronics Hydroclip2 measured grass canopy (8 cm) air temperature and RH.
Radiation instrumentation includes:
• Clear-domed Kipp and Zonen CMP21 pyranometers located at 2 m measured global downwelling, and upwelling components (of wavelength between 0.3-3 μm).
• Kipp and Zonen CG4 pyrgeometers located at 2 m measured the downwelling and upwelling longwave radiation (4.5–40 μm).
• Grass and concrete skin temperatures were measured radiometrically with the Heitronics KT15 pyrometer.

Aerosol and visibility instrumentation includes:

• A Campbell CS120 visiometer located at 2 m measured visual range through air (visibility)
Subsoil instrumentation includes:
• Delta-T ML3 theta probes measured volumetric soil moisture at the surface (0-5 cm) and 10 cm depths.
• Delta-T ST1 thermistor probes measured soil temperature at 1, 4, 10, 17 cm depths.
• Hukseflux HFP01SC flux plate measured ground heat flux (2 cm depth).
