GPP estimates disagree most where foliar nitrogen and carbon gain per leaf area decline: processed data and figure source data

This dataset contains the processed data and derived outputs supporting Figures 1-3, Figures S1-S3, and Tables S1-S2 of the study “GPP estimates disagree most where foliar nitrogen and carbon gain per leaf area decline.” The release includes figure-source CSV files, supplementary-table CSV files, derived GeoTIFF products, figure previews, a data dictionary, processing documentation, validation reports, and a SHA256 integrity manifest. The spatial products use a global 1-degree geographic grid in EPSG:4326. Raw third-party input datasets, including GPP products, LAI, leaf nitrogen, leaf mass per area, PFT, and climate files, are not redistributed. Their source records and access information are documented in the provenance files. The released products are processed and derived outputs intended to support figure inspection and downstream reuse; exact byte-identical reconstruction of all upstream inputs is subject to the availability and terms of the original data providers. The companion analysis code is publicly available at https://github.com/junjunGOGOGO/grl-cpnue-analysis-code and is archived as software at https://doi.org/10.5281/zenodo.21820297.
