Collections of airborne sand are obtained at 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 horizontal flux 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 above
the soil surface are 5, 10, 20, 50, and 100 centimeters for every
location where samples are taken. 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.
