Supercooled liquid is a key component in winter orographic cloud seeding operations. Chemical compounds such as silver iodide serve as nucleating agents in regions where supercooled liquid is present thus resulting in ice formation. As such, determining the presence and location of regions of supercooled liquid is of great interest during cloud seeding operations. Microwave thermodynamic profilers (MTP) provide the ability to observe regions of supercooled liquid through a combination of both temperature and integrated liquid measurements. This study investigates the retrieved MTP characteristic signatures associated with supercooled liquid and seeks to verify the presence of such phenomena through additional remotely sensed ground-based observations.
