Abstract
The Small Ice Detector 2 HIAPER (SID-2H) was used to attempt to detect small ice
particles in the early stages of ice formation in the high liquid water environment of
tropical maritime cumulus clouds sampled during the Ice in Clouds Experiment -
Tropical (ICE-T) field campaign. Its performance in comparison to other probes, and
the development of new corrections applied to the data, are presented. The SID-2H
detected small ice crystals among larger particles. It correctly identified water drops,
and discriminated between round and irregular particle shapes in water-dominated
clouds with errors less than 5%. Remaining uncertainties in the sensing volume, and
the volume over which coincidence of particles occurred, result in the data being used
here in a qualitative manner to identify the presence of ice, its habits and sizes.
