Global Land Surface Evapotranspiration 1982-2016

1.6 GB of global land surface evapotranspiration data produced by the calibration-free Complementary Relationship method. The dataset covers the period from 1982 to 2016 with spatial and temporal resolutions of 0.25-degree and monthly, respectively. It was authored by Ning Ma and is available under a CC-BY-4.0 license.

Use Cases

• Modeling global water cycles based on monthly evapotranspiration estimates.
• Analyzing long-term climate trends based on a 35-year time series.
• Validating hydrological models based on 0.25-degree spatial resolution data.

Strengths

• Covers a 35-year period from 1982 to 2016.
• Provides global coverage at a 0.25-degree spatial resolution.
• Uses a calibration-free method, potentially reducing bias from local parameterization.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the source period.
