| Abstract: |
| An ocean state monitor and analysis radar (OSMAR), developed by Wuhan University in China, have been mounted at six stations along the coasts of East China Sea (ECS) to measure velocities (currents, waves and winds) at the sea surface. Radar-observed surface current is taken as an example to illustrate the operational high-frequency (HF) radar observing and data service platform (OP), presenting an operational flow from data observing, transmitting, processing, visualizing, to end-user service. Three layers (systems):radar observing system (ROS), data service system (DSS) and visualization service system (VSS), as well as the data flow within the platform are introduced. Surface velocities observed at stations are synthesized at the radar data receiving and preprocessing center of the ROS, and transmitted to the DSS, in which the data processing and quality control (QC) are conducted. Users are allowed to browse the processed data on the portal of the DSS, and access to those data files. The VSS aims to better show the data products by displaying the information on a visual globe. By utilizing the OP, the surface currents in East China Sea are monitored, and hourly and seasonal variabilities of them are investigated. |

| 由武汉大学研发的海洋状态监测及分析雷达（OSMAR），被布置于东中国海沿岸的6个雷达站点，用于观测海表面速度（海流，波浪，风）。本研究以雷达观测的流场为例，阐述了一个业务化海表面流雷达观测及数据服务平台，给出了一个从数据获取、传输、处理、可视化以及服务的业务化流程。详细描述了业务化平台中包含三个系统（雷达观测系统、数据服务系统、可视化服务系统），以及各系统间的数据流。各站点获取的流速将在雷达观测系统中数据接收和预处理中心进行集成，然后传输到数据服务系统进行质量控制。用户可以在数据服务系统的主界面上对数据进行浏览，也能够获取这些数据。可视化服务系统能够在球体平台上对数据产品进行直观展示。通过业务化平台可以对东中国海的海流进行实时监测，也能够对海流的日变化以及季节性变化进行研究。 |
