Global Self‐Similar Scaling of Terrestrial Carbon With Aridity

open access: yesGeophysical Research Letters, 2023
While it is well known that water availability controls vegetation growth and soil microbial activity, how aridity affects ecosystem carbon patterns is not completely understood. Toward a more quantitative assessment of terrestrial carbon stocks, here we
