“…sources have been shown to nucleate ice with comparable efficiency (Boose, Welti, et al, 2016;Kaufmann et al, 2016;Niemand et al, 2012), which may indicate that there is a common component of desert dusts that controls its ice-nucleating ability (Atkinson et al, 2013). Mineral dust from deserts is made up of a variety of minerals (Glaccum & Prospero, 1980;Murray et al, 2012), and experiments with specific minerals have shown that the potassium feldspars (K-feldspars) are much more effective at nucleating ice than other tested minerals in desert dusts across the mixed phase-cloud temperature regime (Atkinson et al, 2013;Augustin-Bauditz et al, 2014;Harrison et al, 2016;Kaufmann et al, 2016;Niedermeier et al, 2015;Wex et al, 2014;Whale et al, 2017;Zolles et al, 2015).…”
