Arctic Cloud Summer Expedition (ACSE): University of Leeds Mobotix camera imagery on board Icebreaker Oden

This dataset contains digital imagery from the University of Leed's three 'Mobotix MX-M24M IP' cameras mounted on board the Swedish Icebreaker Oden durning Arctic Cloud Summer Expedition (ACSE). ACSE took place in the Arctic during summer 2014. These imagery were used to complement a suite of other observations taken during the cruise. Those of the UK contribution, as well as selected other data, are available within the associated data collection in the Centre for Environmental Data Analysis (CEDA) archives. Other cruise data may be available in the NOAA ACSE and The Bolin Centre for Climate Research SWERUS (SWEdish-Russian-US) holdings - see online resources linked to this record. The three camera units were mounted pointing in the following directions: - Camera 1: pointing to starboard, - Camera 2: pointing to bow, - Camera 3: pointing to port. The Arctic Cloud Summer Expedition (ACSE) was a collaboration between the University of Leeds, the University of Stockholm, and NOAA-CIRES. ACSE aimed to study the response of Arctic boundary layer cloud to changes in surface conditions in the Arctic Ocean as a working package of the larger Swedish-Russian-US Investigation of Climate, Cryosphere and Carbon interaction (SWERUS-C3) Expedition in Summer 2014. This expedition was a core component to the overall SWERUS-C3 programme and was supported by the Swedish Polar Research Secretariat. ACSE took place during a 3-month cruise of the Swedish Icebreaker Oden from Tromso, Norway to Barrow, Alaska and back over the summer of 2014. During this cruise ACSE scientists measured surface turbulent exchange, boundary layer structure, and cloud properties. Many of the measurements used remote sensing approaches - radar, lidar, and microwave radiometers - to retrieve vertical profiles of the dynamic and microphysical properties of the lower atmosphere and cloud. The UK participation of ACSE was funded by the Natural Environment Research Council (NERC, grant: NE/K011820/1) and involved instrumentation from the Atmospheric Measurement Facility of the UK's National Centre for Atmospheric Science (NCAS AMF).本数据集包含利兹大学（University of Leeds）三台安装于瑞典破冰船奥登号（Swedish Icebreaker Oden）上的Mobotix MX-M24M IP型摄像机采集的数字影像，采集工作随2014年夏季北极云夏季考察队（Arctic Cloud Summer Expedition, ACSE）开展。本次考察于2014年夏季在北极地区进行。该影像数据用于补充本次科考巡航期间获取的多组其他观测数据。英国贡献的观测数据及部分精选其他数据，可在环境数据分析中心（Centre for Environmental Data Analysis, CEDA）档案的关联数据集中获取。其他科考巡航数据可在美国国家海洋和大气管理局北极云夏季考察队（NOAA ACSE）以及博林气候研究中心瑞典-俄罗斯-美国合作项目（SWERUS, Swedish-Russian-US）的档案中获取——详情请见本记录关联的在线资源。 三台摄像机的安装指向如下：1号摄像机指向右舷（starboard），2号摄像机指向船艏（bow），3号摄像机指向左舷（port）。 北极云夏季考察队（ACSE）由利兹大学、斯德哥尔摩大学与NOAA-CIRES联合开展，作为2014年夏季瑞典-俄罗斯-美国气候、冰冻圈与碳相互作用考察计划（Swedish-Russian-US Investigation of Climate, Cryosphere and Carbon Interaction, SWERUS-C3）的子项目，旨在研究北极边界层云对北冰洋地表条件变化的响应。本次考察是SWERUS-C3整体计划的核心组成部分，由瑞典极地研究秘书处（Swedish Polar Research Secretariat）资助支持。 2014年夏季，考察队搭乘瑞典破冰船奥登号开展了为期3个月的巡航，航线从挪威特罗姆瑟（Tromso）出发，前往美国阿拉斯加州巴罗（Barrow）后返航。本次巡航期间，ACSE科考团队开展了地表湍流交换、边界层结构与云属性的观测。其中多数观测采用遥感手段——包括雷达（radar）、激光雷达（lidar）与微波辐射计（microwave radiometers）——以获取低层大气与云的动力学及微物理属性垂直廓线。 ACSE的英国参与项目由自然环境研究委员会（Natural Environment Research Council, NERC，资助编号：NE/K011820/1）资助，并使用了英国国家大气科学中心大气测量设施（National Centre for Atmospheric Science Atmospheric Measurement Facility, NCAS AMF）的观测仪器。
