Description :
Seven techniques designed to measure the dry aeolian deposition of dust on a desert surface were tested during field experiments in Niger. The results show that the crude (unconverted) deposition fluxes of the 5 experimental techniques were similar, while the crude deposition fluxes calculated by the 2 theoretical techniques were substantially higher. The measurements illustrate the need to include a grain shape factor in theoretical dust deposition models. The paper also discusses the advantages and disadvantages of the techniques tested.
