High Altitude MMIC Sounding Radiometer (HAMSR) CPEX-CV

The High Altitude MMIC Sounding Radiometer (HAMSR) CPEX-CV dataset includes measurements gathered by the HAMSR instrument 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. HAMSR has 25 spectral channels which are split into 3 bands to provide measurements that can be used to infer the 3-dimensional distribution of temperature, water vapor, and cloud liquid water profiles in the atmosphere, even in the presence of clouds. Data are available from September 6-30, 2022 in netCDF-4 format.

高海拔毫米波辐射计（High Altitude MMIC Sounding Radiometer，简称 HAMSR）CPEX-CV 数据集收录了在热带对流过程实验——佛得角（Convective Processes Experiment – Cabo Verde，简称 CPEX-CV）野外考察期间，由 HAMSR 仪器收集的测量数据。NASA CPEX-CV 野外考察将于 2022 年 8 月至 9 月在佛得角的萨尔岛展开。此次考察是对 CPEX – 雾霾与风（CPEX-AW）的延续，并搭载在配备了遥感传感器和降流伞发射能力的 NASA DC-8 飞机上进行，这将允许对对流层雾霾、风速、温度、水汽和降水进行测量。CPEX-CV 的总体目标是研究大气动力学、海洋边界层特性、对流、富含沙尘的撒哈拉空气层及其在不同空间尺度上的相互作用，以提高对数据稀缺的热带东大西洋地区过程级生命周期理解和可预测性的认识。HAMSR 拥有 25 个光谱通道，分为 3 个波段，以提供可用于推断大气中温度、水汽和云液态水剖面三维分布的测量值，即使在云层存在的情况下。数据以 netCDF-4 格式于 2022 年 9 月 6 日至 30 日期间可用。
