Short summary

Vegetation growth in semi-arid regions is an important sink for human-induced fossil fuel emissions of CO₂ and this study addresses the strong need for improved understanding and spatially explicit estimates of CO₂ uptake by semi-arid ecosystems. We show that a model incorporating photosynthetic parameters upscaled using satellite-based earth observation simulates CO₂ uptake well for the Sahel, one of the largest semi-arid regions in the world.
