Studies of wind-blown dust have focused on mechanisms of aerosol generation, suspension by wind, and subsequent transport and deposition. To better understand these mechanisms, experiments have been conducted in which fast response aerosol light scattering measurements were taken in conjunction with fast response measurements of vertical and horizontal wind profiles. To supplement these data, we have analyzed LANDSAT satellite image data taken during a Texas dust storm under cloudless conditions. Much can be learned about the aerosol and its transport properties from analyses of the decrease in light scattering from suspended dust transported across a reservoir approximately 150 kilometres from our measurement site. The purpose of this paper is to compare the conclusions drawn from these two data sets. A good comparison was found between deposition velocities and measurements of aerosol surface deposition velocities.
