Sand dunes as potential sources of dust in northern China

Between the fans and large active dunes is a patchwork of bare ground and vegetation, w/ lots of nebkhas (mounds of sand held in place by shrubs). The nebkhas contain more fines and have much more dust emission potential than the fully active dunes: https:

Paper arguing that the active dunes don't produce much dust but dust emission from reactivated aeolian sands can be quite high (though not necessarily the most important sources) https://t.co/Fc0h81HEA5
