This dataset contains time series observations of surface-atmosphere exchanges of carbon, water, and energy, as well as supporting micrometeorological, soil physics, and vegetation measurements. Data have been obtained at ten eddy covariance (EC) flux observation sites across England and Wales. Sites were active for different time periods between 2018 and 2023. Flux data include net ecosystem carbon dioxide exchange (NEE), sensible heat (H), and latent heat (LE). Examples of ancillary and vegetation data include measurements of air temperature, relative humidity, barometric pressure, wind speed and direction, components of radiation, soil heat flux, soil temperature and moisture, precipitation, water table depth, biomass, leaf area index (LAI), and canopy height. This work was supported by the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCAPE programme delivering National Capability.

This repository provides a continuous hydrometeorological record of the Met Office Observation-based research Boundary Layer Facility (BLF) at the semi-rural field site (14 Ha) of Cardington (52° 06′ N, 00° 25′ W, 29 m ± 1 m above mean sea level) in central-southern England between 2004 and 2024. The dataset contains recorded surface meteorology, radiation and subsoil from in-situ sensor measurements at four averaging periods, '01', '05', '10' or '30' minute intervals and measured by instruments mounted on 2 m, 10 m, 25 m and 50 m masts. In addition, specialist remote-sensing instruments including microwave radiometers, Halo Doppler lidars, ceilometers and disdrometer datasets are provided. A full list of NetCDF variables can be found in "Continuous meteorological surface and soil records (2004-2024) at the Met Office surface site of Cardington, UK." Osborne et al. ESSD (2025). This paper also provides a technical introduction to the Cardington site, core instrumentation, specialist radiometers, the land surface model (LSM) forcing dataset derived from the principal dataset and a description of the file formats used in the archived products. This paper should be referenced in any research/publications pertaining to this dataset collection.
