Wind Dust Emission Inventory for the International Border Region of Southern NM

摘要

Numerous windblown dust sources have been identified through satellite image processing during the period between 2000 and 2012. These dust source areas were used to guide wind tunnel sampling campaigns to assess the strength of the dust emissions. We have found that soils characterized as sandy loam and loamy sand equally dominated the soil types sampled. We compared the PM_(10) flux with different sites in terms of soil types and found that the samples collected on sandy soils tend to have higher emissivities than those with sandy-loam and loamy sand. To date, we are in the process of analyzing the complete database and creation of a geospatial database.
