NAMMA CVI CLOUD CONDENSED WATER CONTENT V1

In the NAMMA CVI Cloud Condensed Water Content dataset the counterflow virtual impactor (CVI) was used to measure condensed water content (liquid water or ice in particles about 8 microns in diameter and up) and Cloud Condensation Nuclei (CCN) on the DC-8 during NASA African Monsoon Multidisciplinary Analyses (NAMMA). 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. Water vapor was measured with a MayComm Tunable Diode Laser (TDL) hygrometer and non-volatile particles are examined with an optical particle counter, a condensation nuclei counter, and an impactor for subsequent chemical analyses.

在NAMMA CVI云浓缩水含量数据集中，反流虚拟撞击器（CVI）被用于测量在DC-8上凝结水含量（直径约8微米及以上的颗粒中的液态水或冰）和云凝结核（CCN）。此项任务基于非洲撒哈拉西部海岸350英里之外的佛得角群岛。自2006年8月起，NASA科学家利用地表观测网络和飞机来描述非洲东风波（AEWs）和中尺度对流系统在非洲西部大陆上的演变和结构，及其对区域水能收支的影响。水蒸气使用MayComm可调谐二极管激光（TDL）湿度计进行测量，非挥发性颗粒则通过光学颗粒计数器、凝结核计数器和撞击器进行检测，以备后续化学分析。
