Tracking water vapor homogeneous nucleation and droplet growth with spectroscopy and holography in a free expansion cloud chamber
Cole R. Sagan, Gwenore F. Pokrifka, Samuel M. Koblensky +5
We use a newly commissioned rapid expansion aerosol chamber (REACh) facility to study the homogeneous nucleation of water vapor to form liquid droplets. We perform high-speed measu…

Discovering How Ice Crystals Grow Using Neural ODE's and Symbolic Regression
Kara D. Lamb, Jerry Y. Harrington, Alfred M. Moyle +5
Depositional ice growth is an important process for cirrus cloud evolution, but the physics of ice growth in atmospheric conditions is still poorly understood. One major challenge…
