Radiosondes CPEX-CV

The Radiosonde CPEX-CV dataset was collected 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 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 radiosonde data files include wind direction, dew point temperature, geopotential height, mixing ratio, atmospheric pressure, relative humidity, wind speed, temperature, potential temperature, equivalent potential temperature, and virtual potential temperature measurements at various levels of the troposphere. These data files are available from September 1, 2022, through September 29, 2022 in netCDF-4 format.

本数据集，即 Radiosonde CPEX-CV（对流过程实验 - 佛得角CPEX-CV）数据集，是在对流过程实验 - 佛得角（CPEX-CV）野外考察期间收集的。该NASA CPEX-CV野外考察活动自2022年8月至9月，以佛得角萨尔岛为基地。此次考察活动是对CPEX – 雾霾与风（CPEX-AW）的延续，并在装备有遥感器和降流发射能力的NASA DC-8飞机上进行，这将为测量对流层中的气溶胶、风速、温度、水汽和降水提供可能。CPEX-CV的整体目标是探究大气动力学、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，以提高对数据稀疏的热带东大西洋区域过程级生命周期的理解和可预测性。这些无线电探空数据文件包含风向、露点温度、位势高度、混合比、大气压力、相对湿度、风速、温度、位温、等位温以及虚拟位温等测量值，在对流层的不同高度上。这些数据文件以netCDF-4格式自2022年9月1日至9月29日可供获取。
