Yi Liu, Jingfeng Xiao, Xing Li, and Yue Li

Data sets

A global 0.05 ◦ dataset for gross primary pro- duction of sunlit and shaded vegetation canopies (1992–2020) Wenjun Bi and Yanlian Zhou https://doi.org/10.5061/dryad.dfn2z352k

Long time series (2001-2018) of daily evapotranspiration in China generated based on SEBAL: Part 1 Minghan Cheng https://doi.org/10.5281/zenodo.10803216

Short summary

This work demonstrates that multi-source satellite-based water and carbon fluxes can capture critical soil moisture at a large spatial scale. In particular, grassland and clay with critical soil moisture higher than average soil moisture may be in a state of water limitation for long periods. Increased water demand could expose western grassland to more vulnerability.
