To estimate dust emission is a core task of aeolian parameterization schemes. Over the past decades, many dust emission schemes have been proposed. Here, I give an overview of the scheme development. One of the problems yet to solve is to better model source-limited dust emission. I will present a new model which accounts for the evolution of the supply of soil dust depleted by dust emission and enriched by surface renewal. The impact of source limitation to dust emission can be profound and the process of dust emission is more complex and variable than previously considered.
