Global Land Surface Evapotranspiration, 2000-2022

Global land surface evapotranspiration data produced by the calibration-free Complementary Relationship method. The dataset covers the period from 2000 to 2022 with a spatial resolution of 0.25 degrees and a monthly temporal resolution. 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 hydrological trends based on the 23-year time series
• Validating land surface models based on the 0.25-degree gridded data
• Studying climate change impacts on terrestrial water fluxes based on the post-2000 period coverage

Strengths

• Covers a 23-year period from 2000 to 2022
• Provides global coverage at a 0.25-degree spatial resolution
• Uses a calibration-free method, potentially reducing bias from local parameter tuning

Limitations

• Cannot be combined with Version 1.0 for a longer time series due to different forcings and parameters
• Column-level documentation is absent; field semantics must be inferred after download
