[[Image:|300px|right|link=File:]]The wind-blown (aeolian) transport of sand drives the generation of atmospheric dust and the migration of desert, coastal, and planetary sand dunes. Studies to quantify such aeolian saltation have mostly depended on wind-tunnel, numerical, and analytical methods, whereas there is a relative dearth of high-quality observations of aeolian saltation in natural settings. Here, we help to fill this knowledge gap by presenting a comprehensive dataset on aeolian saltation that includes high-frequency (25-50 Hz) vertical profiles of wind velocity, high-frequency (25 Hz) measurements of relative saltation flux obtained by optical particle counters at multiple heights above the soil bed, and saltation trap absolute measurements of saltation flux and grain size. Our new field dataset includes raw instrumental records, processed time series of meaningful physical variables, and the data processing scripts necessary for all analysis steps. In addition to revealing fundamental aspects about the physics of aeolian saltation, we hope that our novel dataset will be useful for the development and validation of aeolian process models and numerical simulations.
