Anthropogenic and climate‐driven water depletion in Asia

open access: yesGeophysical Research Letters, 2016
Anthropogenic depletion of terrestrial water storage (TWS) can be alleviated in wet years and intensified in dry years, and this wet/dry pattern spanning seasons to years is termed climate variability.
