Near-surface wind-tunnel fugitive dust concentration profiles arising from soil surfaces beds were compared to a finite difference numerical dust transport model. Comparisons of the type shown in this study were previously non-existent in the literat

A key technical challenge for high-altitude (near-space) concepts is autonomous station keeping, or the ability to remain fixed over a geo-location in the presence of winds. Although operational altitudes of 65,000 ft. altitude and above are above we

This is the final report for the year one effort to improve RUSTIC for Coastal, Ocean and Rolling/Rough Terrain Areas. RUSTIC, developed by ITT, is a quasi-CFD wind field modeling software intended for urban domains limited to 2 km x 2 km. This effor

[1] Dust suspension and particle “saltation threshold” speeds were measured in an environmental boundary layer wind tunnel located at the University of California, Davis. The results indicate that dust suspension threshold speeds occur at substan
