The Spatial Variation of Dust Particulate Matter Concentrations during Two Icelandic Dust Storms in 2015
Particulate matter mass concentrations and size fractions of PM1, PM2.5, PM4, PM10, and PM15 measured in transversal horizontal profile of two dust storms in southwestern Iceland are presented. Images from a camera network were used to estimate the visibility and spatial extent of measured dust even...
