measurements of 3-D wind and particle load profiles in dust devils ► Calculation of horizontal profiles of dust devil vertical dust flux ► 85% of sediments lifted by dust devils are coarse grained and are not transported to great heights or long distance ► Dust devils can lift 50 to 1000 kg kmday of dust ► In active regions, dust devils might cause 2.5 to 50 μm of deflation per year
