Field measurements of horizontal forward motion velocities of terrestrial dust devils: Towards a proxy for ambient winds on Mars and Earth

► We measured the speed dust devils (DDs) move across the ground on Earth. ► Long baseline stereo imaging allowed ground motion of >100 DDs to be measured. ► Ambient winds were simultaneously obtained using meteorology masts. ► Time averaged DD velocity correlates well with mean 10 m height ambient wind velocity. ► DDs move 10-20% faster than ambient winds measured at 10 m height.
