Atmospheric observations made at Oliktok Point, Alaska, as part of the Profiling at Oliktok Point to Enhance YOPP Experiments (POPEYE) campaign

摘要

Between 1 July and 30 September 2018, small unmanned aircraftsystems (sUAS), tethered balloon systems (TBSs), and additional radiosondeswere deployed at Oliktok Point, Alaska, to measure the atmosphere in supportof the second special observing period for the Year of Polar Prediction(YOPP). These measurements, collected as part of the Profiling at OliktokPoint to Enhance YOPP Experiments (POPEYE) campaign, targeted quantitiesrelated to enhancing our understanding of boundary layer structure, cloudand aerosol properties and surface–atmosphere exchange and providing extrainformation for model evaluation and improvement work. Over the 3-monthcampaign, a total of 59 DataHawk2 sUAS flights, 52 TBS flights, and 238radiosonde launches were completed as part of POPEYE. The data fromthese coordinated activities provide a comprehensive three-dimensional dataset of the atmospheric state (air temperature, humidity, pressure, andwind), surface skin temperature, aerosol properties, and cloud microphysicalinformation over Oliktok Point. These data sets have been checked forquality and submitted to the US Department of Energy (DOE) AtmosphericRadiation Measurement (ARM) program data archive(http://www.archive.arm.gov/discovery/, last access: July 2019) and are accessible at no cost by allregistered users.
