The growth, lifetime, number density, and size of water droplets in warm atmospheric clouds determine the evolution, lifetime and light transmission properties of those clouds. These small-scale cloud properties, in addition to precipitation initiation, have strong implications for the Earth's energy budget since warm clouds cover large geographic areas. To understand these small scale processes, we have devloped the Max Planck CloudKite to measure cloud micropshyics and turbuelnce at high spatial/temporal resolutions. This is achieved by perfoming airborne high-speed holography and particle image velocimetry inside clouds. In this talk, I will introduce the CloudKite platform and present the imaging measurements within shallow cumulus clouds over the Atlantic near Barbados. Our observations reveal strong local droplet clustering on sub-meter scales, challenging long-held assumptions about cloud microphysics and carrying important implications for weather and climate modelling.
