Airborne Precipitation Radar 3rd Generation (APR-3) CPEX-CV

The Airborne Precipitation Radar 3rd Generation (APR-3) CPEX-CV dataset consists of radar reflectivity, Doppler velocity for all bands, linear depolarization ratio Ku-band, and normalized radar cross-section measurements at Ka- and Ku- bands data collected by the APR-3 onboard the NASA DC-8 aircraft. These data were gathered during the Convective Processes Experiment – Cabo Verde (CPEX-CV) field campaign. The NASA CPEX-CV field campaign will be 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 was 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 September 30, 2022, in netCDF-4 format, with associated browse imagery in JPG format.

该航空降水雷达第三代（APR-3）CPEX-CV数据集包含由NASA DC-8飞机搭载的APR-3雷达收集的所有波段的雷达反射率、多普勒速度、Ku波段线性去极化比以及Ka和Ku波段的归一化雷达截面测量数据。这些数据是在对流过程实验——佛得角（CPEX-CV）现场活动中收集的。NASA CPEX-CV现场活动将于2022年8月至9月在佛得角的萨尔岛展开。此次活动是对CPEX-气溶胶和风（CPEX-AW）的延续，并在配备有远程传感器和投掷式探空仪发射能力的NASA DC-8飞机上进行，这将允许测量对流层气溶胶、风速、温度、水汽和降水。CPEX-CV的总体目标是研究大气动力学、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，以提高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9月30日止，以netCDF-4格式提供，并附带JPG格式的浏览图像。
