This document contains crucial data recorded by the CPL (Cloud Physics Lidar) on September 11 and 27, 2012, detailing the phase state of water (liquid and ice) in relation to storm center positions. It includes an examination of various layer heights and observations of atmospheric conditions during the event. Additionally, it outlines key lessons learned by the CPL team regarding equipment operation and communication protocols in extreme weather conditions, highlighting the importance of real-time image feedback from ground crews.

Lessons Learned – CPL Team • PMOF too cold! • CPL will overheat if powered on and there is a takeoff delay. • Must make sure communications with ground crew are clear and finalized. • Do groups have feedback on utility of CPL real-time images?
