Dust aerosol is an important atmospheric component due to its ice nucleating ability, which affects cloud phase and precipitation. Arizona Test Dust (ATD) is often used as a proxy for environmental dust aerosol in laboratory studies. In this work, we examine how the ice nucleating behavior of ATD is altered with different solution phase and dry aging processes under several conditions. We find that ATD ice nucleating ability is degraded in significant ways under most conditions, including aging for less than a day in deionized water or NaCl solution. Additional studies are detailed for processing in acidic solutions, salt solutions, peroxide treatment, heat treatment, and protease enzyme treatment. We find evidence of warm-temperature ice nucleating particles that share the analytically characteristic attributes of organic ice nucleators but are heat stable beyond the normal range for organic materials. We hypothesize that this is due to binding and stabilization of organic materials at the mineral surface.
