NAMMA Raw DC-8 Dropsonde V1

The NAMMA Raw DC-8 Dropsonde dataset consists of high-resolution vertical profiles of ambient pressure, temperature, relative humidity, wind speed, and wind direction obtained by the DC-8 dropsonde system during the NASA African Monsoon Multidisciplinary Analyses (NAMMA) field campaign. The NAMMA field campaign was based in the Cape Verde Island, 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. The DC-8 dropsonde system uses an integrated, highly accurate, Global Positioning System (GPS)-located atmospheric profiling dropsonde measuring and recording current atmospheric conditions in a vertical column below the aircraft. Data files are available in ASCII format for the period of August 7, 2006 through September 12, 2006.

NAMMA 原始 DC-8 投掷式探空仪数据集包含了由 NASA 非洲季风多学科分析（NAMMA）现场考察期间，通过 DC-8 投掷式探空仪系统获得的高分辨率环境大气垂直剖面，其中包括环境气压、温度、相对湿度、风速和风向。该现场考察以佛得角群岛为基地，位于西非塞内加尔海岸350英里之外。自2006年8月起，NASA科学家运用地表观测网络和飞机，对西非大陆上空非洲东风波（AEWs）和中尺度对流系统（Mesoscale Convective Systems）的演变与结构进行了描述，并探讨了它们对区域水资源和能量收支的影响。DC-8投掷式探空仪系统利用集成的、高精度的全球定位系统（GPS）定位大气剖面投掷式探空仪，对飞机下方垂直柱内的当前大气条件进行测量和记录。数据文件以 ASCII 格式提供，时间范围为2006年8月7日至2006年9月12日。
