Aerial Assessment of Liquid in Clouds at Oliktok (AALCO) Intensive Operation Period (IOP) began in October, 2016 and ended in October, 2017 at the ARM Mobile Facility-3 (AMF-3) at Oliktok Point, Alaska. The operations tested super-cooled liquid water sensors (SLWCs), leaf-wetness sensors, radiosondes, and a distributed temperature sensor (DTS) on tethered balloon system (TBS) platforms throughout the period. An auto-reeler system, a helikite, and a aerostat were tested. When conditions were optimal, the aerostat was preferred to the helikite and the auto-reeler. It was found the SLWCs had better transmission and sensitivity to relay information about the near-surface cloudy boundary layer than the leaf-wetness sensors. The DTS was also found to give useful information about the atmospheric column and deployment is condition-dependent. Results from the SLWCs and DTS are being compared with high resolution Large Eddy Simulations (LES) in the System for Atmospheric Modeling (SAM).
