Sub-daily actual evapotranspiration data for 45 monitoring sites (2014-2024) [COSMOS-UK]

This dataset provides derived measurements of land-atmosphere energy and water exchanges from selected COSMOS-UK environmental monitoring sites across the United Kingdom, collected between 2014 and 2024. It contains estimates of sensible heat flux (H), latent heat flux (LE), and evapotranspiration (ET), alongside supporting hydrometeorological and soil physics variables, enabling detailed analysis of surface energy balance and water fluxes. The data cover 45 COSMOS-UK sites, where a 3D sonic ane

What's in it

Data offered docs-verified: sensible heat flux (H) · latent heat flux (LE) · evapotranspiration (ET) · supporting hydrometeorological variables · soil physics variables · quality-controlled and non-quality-controlled flux and ancillary variables · site metadata · dynamic metadata (instrumentation and land cover changes) · variable dictionary

Useful for

Use cases llm-inferred: Calibrating or validating modelled evapotranspiration in catchment water-balance studies for FRA or drought assessments · Benchmarking ET and latent/sensible heat fluxes against eddy-covariance observations for hydrological or land-surface model evaluation · Comparing site-level ET across UK land cover types to inform land-use change impacts on water balance
Audience llm-inferred: hydrologists · flood consultants · water resources engineers · environmental modellers · micrometeorologists · catchment scientists

Limitations

Constraints llm-inferred: Point-based measurements at 45 sites only; not spatially continuous and not gridded · Only sites with an operational 3D sonic anemometer and no instrumentation or telemetry faults are included · Only simple quality control applied; a subset of variables is quality-controlled, so users must assess suitability · Tabular CSV without spatial geometry; spatial analysis requires joining site metadata · Temporal extent ends 2024-12-31, so it does not cover later years · Derived from 20 Hz data via EddyPro v7.0.9, so processing choices affect outputs
