Short summary
Earth system models are essential tools for predicting windblown dust emissions from global drylands. These models show large discrepancies in simulating the interannual variability of historical dust emissions, as well as the relative importance of wind speed versus hydroclimate drivers. This study underscores the need to improve near-surface wind simulations in hyperarid areas and land surface process representations in arid and semiarid areas to reduce dust emission uncertainties.
