DC-8 Meteorological and Navigation Data CPEX-CV

The DC-8 Meteorological and Navigation Data CPEX-CV dataset is a subset of airborne measurements that include GPS positioning and trajectory data, aircraft orientation, and atmospheric state measurements of temperature, pressure, water vapor, and horizontal winds. These data were gathered during the Convective Processes Experiment – Cabo Verde (CPEX-CV) field campaign. The NASA CPEX-CV field campaign was based out of Sal Island, Cabo Verde from August through September 2022. The campaign is a continuation of CPEX – Aerosols and Winds (CPEX-AW) and will be conducted aboard the NASA DC-8 aircraft equipped with remote sensors and dropsonde-launch capability that will allow for the measurement of tropospheric aerosols, winds, temperature, water vapor, and precipitation. The overarching CPEX-CV goal was to investigate atmospheric dynamics, marine boundary layer properties, convection, the dust-laden Saharan Air Layer, and their interactions across various spatial scales to improve understanding and predictability of process-level lifecycles in the data-sparse tropical East Atlantic region. These data files are available from September 2, 2022, through October 3, 2022, in ASCII format.DC-8气象与导航数据集（CPEX-CV）系由空中测量数据构成的一个子集，其中包括全球定位系统（GPS）定位与轨迹数据、飞机姿态以及大气状态测量，涉及温度、气压、水汽和水平风速等参数。这些数据收集于对流过程实验——佛得角（CPEX-CV）野外考察期间。NASA CPEX-CV野外考察活动于2022年8月至9月基于佛得角的萨尔岛展开。此次考察是对CPEX-气溶胶与风（CPEX-AW）的延续，将在配备有远程传感器和落球释放能力的NASA DC-8飞机上进行，这将允许可测量的对流层气溶胶、风速、温度、水汽和降水。CPEX-CV的整体目标旨在研究大气动力学、海洋边界层特性、对流、沙尘富含的撒哈拉空气层及其在不同空间尺度上的相互作用，以提升对数据稀疏的热带东大西洋地区过程级生命周期的理解与可预测性。这些数据文件自2022年9月2日起至10月3日止，以ASCII格式提供。
