Recent in situ observations suggest that mixed phase regimes, here defined as limited cloud volumes containing both liquid and solid water, are constrained to narrow layers (order 100 m) separating all liquid and fully glaciated volumes. We present in situ and surface based remote sensing data from the Mixed-Phase Arctic Cloud Experiment to discuss the fine-scale structure of the mixed-phase clouds observed during this experiment, and show that, while these clouds were characterized by regions dominated by one of the two phases, both phases were present most of the time. We also present observations taken in Madison, Wisconsin of layered mixed-phase clouds to confirm that our observations are not just an Arctic phenomenon.
