NAMMA NASA POLARIMETRIC DOPPLER WEATHER RADAR (NPOL) V1

The NAMMA NASA Polarimetric Doppler Weather Radar (NPOL) dataset used the NPOL, developed by a research team from Wallops Flight Facility, is a fully transportable and self-contained S-band research radar that collected and operated nearly continuously during NAMMA. Data was collected 19 August through 30 September 2006, at Kawsara, Senegal. Its continuous operation provides a full volume scan every fifteen minutes. Scans may be either 270 Km long range scans or 150 Km range for most high resolution data scans. Products available include real time PPI scans of reflectivities and velocities, and near real time displays of other radar products, including RHI's, CAPPI's, and Polarimetric products. Browse imagery is available for PPI reflectivities. 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 NASA极化多普勒天气雷达（NPOL）数据集，由沃尔lops飞行设施的研究团队开发的NPOL雷达，是一款全可携且自给自足的S波段研究雷达，在NAMMA期间进行了近乎连续的数据收集与操作。数据收集时间自2006年8月19日至9月30日，地点位于塞内加尔的Kawsara。其连续运行模式每十五分钟提供一次完整体积扫描。扫描可能为270公里长的远程扫描，或150公里的远程扫描，以获取大部分高分辨率数据扫描。可用的产品包括实时PPI反射率和速度扫描，以及近乎实时的其他雷达产品显示，包括垂直剖面（RHI）、体积扫描（CAPPI）和极化产品。PPI反射率浏览图像亦可供使用。这些数据文件是在支持NASA非洲季风多学科分析（NAMMA）行动期间生成的，该行动是一项由美国国家航空航天局（NASA）科学任务局资助的现场研究调查。此次任务以佛得角群岛为基地，位于非洲西部塞内加尔海岸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表征非洲东风波（AEWs）和中尺度对流系统在西非大陆上的演变和结构，及其对区域水循环和能量收支的影响。
