ABSTRACT:
A sampler suitable for collecting airborne dust under natural field conditions was developed at Big Spring, Texas, in a laboratory wind tunnel. The sampler, BSNE, will collect at least 86% of the material passing the 10-cm2 opening and retain an average of 96% of the material entering the opening. Fifty-two of the samplers were constructed and placed in highly erodible fields. No significant problems were encountered in determining soil loss except the need to measure the distance between the sampler and the soil surface after each dust storm.
