During the measurement campaign FROST (FReezing Of duST), LACIS (Leipzig Aerosol
Cloud Interaction Simulator) was used to investigate the immersion freezing behavior of size
selected, coated and uncoated Arizona Test Dust (ATD) particles with a mobility diameter of
300 nm. Particles were coated with succinic acid (C 4 H 6 O 4), sulfuric acid (H 2 SO 4) and
ammonium sulfate ((NH 4) 2 SO 4). Ice fractions at mixed-phase cloud temperatures ranging
from 233.15 K to 239.15 K (±0.60 K) were determined for all types of particles. In this …

Cloud Interaction Simulator) was used to investigate the immersion freezing behavior of
coated and uncoated Arizona Test Dust (ATD) particles with a mobility diameter of 300nm.
Particles were coated with succinic acid (C4H6O4), sulfuric acid 5 (H2SO4, two different
coating conditions), and ammonium sulfate ((NH4) 2SO4). Ice fractions at temperatures
between 233.15 K and 240.65 K were determined for all types of particles acting as IN (Ice …
