NAMMA TOGA RADAR DATA V1

The NAMMA TOGA Radar Data dataset consists of a collection of products derived from the NASA TOGA radar observations that were collected in the Republic of Cape Verde during the NAMMA campaign. The NASA TOGA radar is a C-band scanning radar with a beam width of 1.65 degrees. The radar was deployed on the southern tip of Sao Tiago (14.92N, 23.48W), the southern-most island in the Cape Verde islands. The radar operated nearly continuously from 15 August through 16 September, 2006, collecting measurements of horizontal radar reflectivity (ZH), radial velocity (VR) and spectral width (SW). 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 TOGA雷达数据集由一系列产品组成，这些产品源自美国宇航局（NASA）TOGA雷达在佛得角共和国NAMMA活动期间所收集的观测数据。NASA TOGA雷达为一部C波段扫描雷达，其波束宽度为1.65度。该雷达部署在圣蒂亚戈岛（14.92N，23.48W）的南端，该岛是佛得角群岛中最南端的岛屿。雷达从2006年8月15日到9月16日几乎连续运行，收集了水平雷达反射率（ZH）、径向速度（VR）和频谱宽度（SW）的测量数据。这些数据文件是在支持美国宇航局非洲季风多学科分析（NAMMA）活动期间生成的，该活动是由美国宇航局（NASA）科学任务部资助的现场研究调查。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月起，NASA科学家利用地表观测网络和飞机，对西非大陆上空非洲东风波（AEWs）和中小尺度对流系统（Mesoscale Convective Systems）的演变和结构进行表征，并研究其与区域水资源和能量收支的相关影响。
