Fig. 6From: Dust emission source characterization for visibility hazard assessment on Lordsburg Playa in Southwestern New Mexico, USAPI-SWERL test response curve showing no PM10 supply limitations once threshold friction velocity (u*t) has been exceeded. The dashed line represents the friction velocity (u*) and the solid line is the instantaneous vertical flux of PM10. This test was from the western beach area (WPL)Back to article page
