ABSTRACT
We have designed and tested two types of passive collectors to study aeolian erosion in the
field. The first passive sampler is a sticky pad that allows for directional particulate
assessment by an automatic particle counting procedure. The second one features an omnidirectional
capture opening, and mass of retained particles is gravimetrically quantified.
Vertical arrays of these passive collectors have been constructed to obtain vertical profiles of
the horizontal particle flux as a function of soil properties, nearby sources and wind speed.
We present some first results from field campaigns
