A model for mineral dust emission
Abstract
In the new dust emission model presented in this paper, the two major dust emission mechanisms are considered, namely, saltation bombardment and aggregates disintegration. The emission of dust generated by the first mechanism is modeled from the perspective of volume removal caused by saltating particles and that arising from the second mechanism is related to the streamwise saltation flux. The dust emission rate is constrained by using the information of minimally and fully dispersed particle size distributions. The performance of the dust emission model is compared with the available field measurements. Despite large uncertainties both in measurements and model parameters, the comparison shows that the model is promising. The accuracy of the model depends on the availability of high‐quality particle size data. It is proposed to establish a detailed database of particle size distributions for various soil types for the purpose of modeling dust emission over large areas.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
