欧洲正在运行的天气雷达网络覆盖30多个国家，包含200多台天气雷达。雷达网络在硬件、信号处理、发射/接收频率和扫描策略上都是不同的，因此它与下一代天气雷达(NEXRAD)网络有根本的不同。另一个不同之处在于，欧洲天气雷达网的密度大约是NEXRAD网的两倍。在欧洲国家气象局(EUMETNET)内，气象雷达信息交换业务方案(OPERA)是一组服务，自1999年以来一直致力于改进雷达及其测量的协调。此外，OPERA除其他外，通过开发雷达数据信息模型和共同商定的数据格式，促进和促进了其成员之间的雷达数据交流。自2011年以来，一个雷达数据中心(“奥德赛”)一直在运行，根据体积数据生成全网雷达马赛克。OPERA工作的一个重要部分是记录成员在雷达操作和数据制作方面的最佳做法，并提出联合建议：例如，关于其他微波源造成的干扰和风力涡轮机造成的干扰。因此，向所有成员提供最有经验的成员的专门知识，支持整个网络的发展。最近的工作产生了关于制作雷达数据的最佳做法、质量指标和使用极化雷达的经验的报告。所有这些报告和建议都在OPERA网站上公开提供，供更广泛的气象界使用。
The operational weather radar network in Europe covers more than 30 countries and contains more than 200 weather radars. The radar network is heterogeneous in hardware, signal processing, transmit/receive frequency, and scanning strategy, thus making it fundamentally different than the Next Generation Weather Radar (NEXRAD) network. Another difference is that the density of the European weather radar network is roughly twice that of the NEXRAD network. Within the European National Meteorological Services (EUMETNET), a grouping of services, the Operational Program for Exchange of Weather Radar Information (OPERA) has been working since 1999 on improving the harmonization of radars and their measurements. In addition, OPERA has facilitated and stimulated the exchange of radar data between its members, among others, by the development of a radar data information model and jointly agreed data formats. Since 2011, a radar data center ("Odyssey") has been in operation, producing network-wide radar mosaics from volumetric data. An essential part of the OPERA work is the documentation of the members' best practices in radar operation and data production and the making of joint recommendations: for example, on the interferences caused by other microwave sources and the disturbances caused by wind turbines. Hence, the expertise of the most experienced members is made available to all members supporting the development of the network as a whole. Recent work has produced reports on best practices for production of radar data, on quality indicators, and on experiences with the use of polarimetric radars. All of these reports and recommendations are publicly available on the OPERA website, for use by the wider meteorological community.
