The perfect low cloud

The ideal model cloud

On the flight on 29 April, we found the ideal textbook cloud: an extensive low-level mixed-phase cloud with clear sky above it. This is what one-dimensional radiative transfer models have been written for! In this cloud, we found liquid droplets that were 20 micrometers large on the top and 10 micrometers at the bottom. Toward the bottom, ice crystals were also found in this cloud.
