New Data Product Determines Thermodynamic Phase of Cloud Hydrometeors
Thermodynamic cloud phase identification is important to understand many cloud processes such as ice particle production, precipitation formation, and cloud life-cycle evolution, and it is essential to improve our understanding of cloud radiative properties and the atmospheric radiative budget. Because ice particles and liquid droplets have distinct sizes, shapes, fall velocities, and refractive indexes, clouds…
