Mass Conservation-Constrained Estimates of Terrestrial Gross Primary Production, Net Ecosystem Exchange, and Ecosystem Respiration (opens in new tab)

Gross primary production (GPP), net ecosystem exchange (NEE), and ecosystem respiration (RECO) are essential components in the carbon cycle of global terrestrial ecosystems. Satellite remote sensing (RS) provides a unique means to retrieve these three carbon fluxes at regional and global scales. However, there remains a significant challenge to ensure both high estimation accuracy and carbon budget balance in current RS models. In this study, for the first time, we propose an innovative mass ...
