Global variation in vegetation carbon use efficiency inferred from eddy covariance observations

This dataset includes the vegetation carbon use efficiency (CUE) for global eddy covariance sites, a gridded global vegetation CUE map, and the code to estimate CUE from eddy covariance observations. For more details on scientific implications, methodology and validation, please refer to the manuscript:

Luo, X., Zhao, R., Chu, H., Collalti, A., Fatichi, S., Keenan, T., Lu, X., Nguyen, N., Prentice, I.C., Sun, Wu., Yu, K. & Yu, L. (2025). Gloabl variaiton in vegetation carbon use efficiency inferred from eddy covariance observations. Nature Ecology & Evolution. DOI: 10.1038/s41559-025-02753-0.

The dataset includes the following items:

1. "CUE_fluxnet-v1.zip" is the code to estimate CUE from eddy covariance observations.   
2. "CUE_EC_site_032025.xlsx" contains the site-specific CUE and other parameters related to autotrophic respiration, as well as the uncertainties of those parameters.
3. "CUE_EC_032025.nc" includes a gridded global CUE map (CUE_EC) and its uncertainty at 0.5 degree. The .nc file also includes the CUE estimates from an ensemble of dynamic global vegetation models (DGVMs).
4. "Source Data_Figures.xlsx" includes the source data to generate the main figures in the publication.
