CLMS Evapotranspiration (ETA) Global 300m 10-daily V1 (COG)
Provides actual evapotranspiration, soil evaporation and canopy transpiration with some quality indicators. Estimates are provided for two evapotranspiration schemes and an Ensemble of models. The 10-daily estimates are available at global scale in the spatial resolution of 300 m from November 2025 to present, derived from Sentinel-3 OLCI and SLSTR data.

Useful for
- Use cases llm-inferred
- Evapotranspiration term for catchment water-balance inputs in FRA or water resources assessments · Irrigation and crop-water demand context for agricultural drainage or land-use change assessments · Drought and soil-moisture stress screening for ecological baseline assessments · Regional evaporation comparison for hydrological model calibration and sense-checking

Limitations
- Constraints docs-verified
- ET not modelled over cloud, snow, or non-converged pixels · ET not modelled over inland open-water pixels · Very high uncertainty in urban pixels · Gap-filled values where cloud-free observations are missing · Global 300 m grid is coarse for site-scale drainage or FRA work · Asset download references OIDC/S3 authentication
