Integrating Sub-Centimeter Resolution Photogrammetry with a Surface Roughness Correction Factor Applied to PI-SWERL Measurements
… Portable In-situ Wind Erosion Laboratory (i.e., PI-SWERL) along with existing limitations for adjusting dust emission measurements for microtopographic surface roughness. A new method for characterizing the surface roughness correction factor, alpha (α), is introduced to address these …

Aeolian dust emission dynamics across spatial scales: landforms, controls and characteristics
… modification of the hydrological systems. A PI-SWERL (Portable In-Situ Wind ERosion Lab) wind tunnel was used to measure the emission potential of the Landsat derived targets. The most emissive sources were paleostockpiles of alluvial silt deposits and associated degraded nebkhas within the …

The nature of pan sediments: A case study on dust supply from the Makgadikgadi pans, Botswana
… samples collected using frisbees, BSNE traps and PI-SWERL exhaust, between July and October 2011. Dry sieving and laser diffraction for all 41 samples revealed a dominance of uni-modal, sand sized sediments, with the particle size distribution controlled by evaporite minerals, inferred from sample …
