Stocker et al. investigated the effect of dry soil on GPP across scales after isolating from the effect of VPD. I read this paper, wondering the global error distribution is associated with my global TWS IAV error map.
Message: Soil moisture should be included as a GPP estimator as VPD alone cannot account for dry soil impact on GPP Dry soil effect reduces the global annual GPP by 15% The effect of dry soil decreases with increasing spatial scale, due to compensation from different regions.
