A comprehensive dataset of vegetation indices, simulated GPP, and GOSIF product across 76 flux tower sites

This dataset consolidates multi-source vegetation and productivity data from 76 eddy covariance flux tower sites globally. It is designed to serve as a benchmark for validating and improving terrestrial carbon cycle models and remote sensing GPP algorithms. The dataset harmonizes site-level vegetation indices (VIs), remote sensing-based model simulated GPP, and the global GOSIF product for easy cross-comparison.
