NAMMA TWO-DIMENSIONAL STEREO PROBE AND CLOUD PARTICLE IMAGER V1

The NAMMA Two-Dimensional Stereo Probe and Cloud Particle Imager dataset consists of data from two probes used to measure the size, shape, and concentration of cloud particles; the two-dimensional stereo probe (2D-S), and the cloud particle imager (CPI). Both of these probes measure particle size distributions and derives extinction, particle concentration, ice water content and particle shape. Both probes provide hi-resolution black and white images of cloud particles. These data files were generated during support of the NASA African Monsoon Multidisciplinary Analyses (NAMMA) campaign, a field research investigation sponsored by the Science Mission Directorate of the National Aeronautics and Space Administration (NASA). This mission was based in the Cape Verde Islands, 350 miles off the coast of Senegal in west Africa. Commencing in August 2006, NASA scientists employed surface observation networks and aircraft to characterize the evolution and structure of African Easterly Waves (AEWs) and Mesoscale Convective Systems over continental western Africa, and their associated impacts on regional water and energy budgets.

NAMMA二维立体探针与云粒子成像仪数据集由两个用于测量云粒子尺寸、形状和浓度的探针所收集的数据组成，分别为二维立体探针（2D-S）和云粒子成像仪（CPI）。这两个探针均用于测量粒子尺寸分布，并推导出消光系数、粒子浓度、冰水含量以及粒子形状。两者均提供高分辨率的黑白云粒子图像。这些数据文件是在支持美国国家航空航天局（NASA）非洲季风多学科分析（NAMMA）任务期间生成的，该任务由美国国家航空航天局（NASA）科学任务局资助，是一项实地研究调查。该任务以佛得角群岛为基地，位于西非塞内加尔海岸350英里处。自2006年8月起，NASA科学家利用地面观测网络和飞机来表征西非大陆上空非洲东风波（AEWs）和中尺度对流系统（MCS）的演变和结构，以及它们对区域水循环和能量平衡的影响。
