“…Transported dust can also have a different composition further away from the source. Globally, when compared to other types of mineral dusts, such as Saharan dusts or Gobi dust (Joshi et al, 2017), the amount of silicon in all five v-dust samples is considerably lower while the amount of iron, magnesium, and titanium is higher (Romanias et al, 2016), (Langmann, 2013).…”

“…To determine SSA, the Brunauer-Emmett-Teller (BET) method was employed. Nitrogen (N 2 ) adsorption measurements were performed with a laboratory gas sorption analysis system (Joshi et al, 2017), (Ibrahim et al, 2018) within 0.05-0.3 relative pressure range (P/P 0 ) of N 2 . To determine the range of uncertainty, three adsorption measurements were conducted for each sample.…”

“…The intensity of the third peak at 2100-2200 cm −1 , attributed to the association mode of H-O-H, was much smaller (Ma et al, 2010a). It is possible but non-trivial to convert IR absorbance to the amount of adsorbed water, and the procedure used can be found elsewhere (Goodman et al, 2001;Ma et al, 2010a;Joshi et al, 2017;Ibrahim et al, 2018). It was found that the threeparameter BET equation (Joyner et al, 1945) could well describe water adsorption as a function of RH on mineral oxides (such as SiO 2 , TiO 2 , Al 2 O 3 , and MgO) (Goodman et al, 2001;Ma et al, 2010a;Joshi et al, 2017), authentic mineral dust from different sources (Joshi et al, 2017;Ibrahim et al, 2018) and Icelandic volcanic ash (Joshi et al, 2017).…”
