NAMMA DC-8 DROPSONDE V1

The NAMMA DC-8 Dropsonde dataset were collected by the DC-8 dropsonde system, which uses an integrated, highly accurate, GPS-located atmospheric profiling dropsonde measuring and recording current atmospheric conditions in a vertical column below the aircraft. hese dropsondes, also known as dropwindsondes or parachute radiosondes, are small, lightweight (less than 1 lb) cylindrical instruments that fall freely through the atmosphere, slowed somewhat by a small inflatable parachute. 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 DC-8 气象探测仪数据集由DC-8气象探测仪系统收集，该系统集成了高精度、GPS定位的大气剖分气象探测仪，用于测量和记录飞机下方垂直柱状大气中的当前大气条件。这些气象探测仪，亦称为气象探测仪或降落伞无线电探空仪，是小型、轻便（重量小于1磅）的圆柱形仪器，在自由下落过程中受到小型充气降落伞的一定减速。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，该任务由国家航空航天局（NASA）科学任务部赞助的实地研究调查。此次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月开始，NASA科学家利用地表观测网络和飞机来描述非洲东风波（AEW）和中尺度对流系统在大陆西非的演变和结构，以及它们对区域水资源和能量收支的影响。
