Master tracks in 1 Hz temporal resolution from the HALO research aircraft flight HALO_220410a (RF16)@en

During the HALO-(AC)³ campaign in March-April 2022 airborne observations were performed with the High Altitude and LOng range research aircraft (HALO) covering the Fram Strait and north polar regions. The flight tracks covered open ocean areas, the marginal sea ice zone, and closed sea ice cover. Furthermore, cloud conditions were observed during air mass transformation events as marine cold air outbreaks and warm air intrusions. This data set summarizes the flight tracks of HALO and provides longitude, latitude, and altitude defined as position above WGS84. All data are measured by the Basic HALO Measurement and Data System (BAHAMAS) and resampled to 1 Hz temporal resolution.2022年3月至4月开展的HALO-(AC)³科考航次中，研究团队依托高海拔长航程科研飞机（High Altitude and LOng range research aircraft，HALO）完成了机载观测作业，观测覆盖弗拉姆海峡（Fram Strait）与北极北部海域。本次航次的飞行轨迹涵盖开阔洋区、边缘海冰带以及全封闭海冰覆盖区。此外，研究团队在气团转化事件（包括海洋性冷空气爆发与暖空气侵入过程）期间同步记录了云系状况。本数据集汇总了HALO的飞行轨迹信息，并提供基于WGS84大地坐标系的经度、纬度与海拔高度数据。所有观测数据均由HALO基础测量与数据系统（Basic HALO Measurement and Data System，BAHAMAS）采集，并被重采样至1赫兹的时间分辨率。
