Short summary
Uncertainty in dust emission estimates stems from simplified surface parameterizations. We incorporate dynamic vegetation cover into the dust emission scheme of an Earth System Model. Including vegetation reduces global dust emissions by 23 % and redistributes regional contributions by suppressing emissions in grass-covered dryland, improving agreement with observations of the global dust cycle. This work establishes a framework for advancing the representation of land–atmosphere feedbacks.
