Atmospheric desert dust was collected over 36 months in ground-level collectors at four stations in the northern Negev desert, Israel. Three stations (Shivta, Sede Boqer and Avdat) are located in the desert itself whereas the fourth station (Sayeret Shaked) is situated at the desert fringe, in the transition zone between the true desert and the more humid area to the north. The dynamics of the dust in the three desert stations is similar and differs from that at the desert fringe station. In the desert, dust accumulation is highest in summer and lowest in winter, whereas the situation is reverse at the desert fringe. Also, the amount of accumulation is much higher in the desert itself. No important differences are observed with respect to the average grain size of the dust, but the temporal evolution in grain size variability at the desert fringe is different from that in the desert.
