Description

Unmanned Aerial Systems (UAS) are an emerging technology for atmospheric in situ sampling. The Atmospheric Radiation Measurement (ARM) Aerial Facility (AAF) operated the DataHawk II, a lightweight, fixed-wing platform developed by the University of Colorado Boulder, in Oliktok, AK, as part of the POPEYE campaign (Profiles at Oliktok Point to Enhance YOPP Experiments). The DataHawk II had a suite of miniaturized instruments that measured position, temperature, pressure, relative humidity, and winds. A total of 54 flights were flown in summer 2018, continuously profiling from 50-1000m and loitering at cloud base. This work examines the ability to analyze fine-scale turbulence parameters from on board sensors, using a processing routine developed by Dale Lawrence and Abhiram Doddi. This dataset will add insight into turbulent atmospheric structures and cloud base turbulence in the Arctic.
