Characteristics of ice nucleating particles from the longârange transport of Saharan dust
Listed in National Center for Atmospheric Research
Transported mineral dust in a Saharan air layer (SAL) contains active ice‐nucleating particles (INPs) that may be transported across the Atlantic Ocean and subsequently seed clouds in the Caribbean and the Americas.
Description
During an aircraft campaign around Houston and the western U.S. Gulf Coast, a widespread SAL advected into the sampling region allowing for measurement of the ice‐nucleating ability of SD following long‐range transport.
Results showed that the mean INP concentrations were 3–4.5 times higher than non‐Saharan dust (nSD), but only at temperatures <−21°C. Active surface site densities were also enhanced in the SD, exceeding the mean for nSD by over an order of magnitude at temperatures <−21°C. These INP measurements confirmed that SD remains an active INP even after >8,000 km westward transport across the Atlantic Ocean.
