Abstract: 

Collections of airborne sand are obtained at 16 locations at the Jornada LTER area, the 15 NPP sites and the Geomet site. The collections are taken using BSNE collectors. The collectors are turned into the wind with wind vanes. The amount of material collected corresponds to the horizontalflux at the height of the collector and the opening area of the collector and the duration of the sampling time.

The five heights of the BSNE collectors are 5, 10, 20, 50, and 100 centimeters for every location where samples are taken. The collected amounts are fitted to a function m(z) = a exp(bz +czz) where m(z) is the mass of sand collected, z is height above ground, and a, b, and c are constants. The hypothesis of the experiment is that the vertical flux of the particles smaller than 10 micrometers is a constant ratio of the horizontal sand flux. The objectives of the experiment are to find patterns of sand flux rates as affected by soil and vegetation.
