SuperDARN Meteor Winds 2018-2021 (plus bonuses)

SuperDARN meteor wind data *.m.* - meridional (+ve Poleward) *.z.* - zonal (+ve East) X/Y are in radar coordinates - most users can disregard. Supported by NSF #1934973 Collaborative Research: Super Dual Auroral Radar Network (SuperDARN) Operations, Research and Community Support SuperDARN is an international collaboration operating high frequency (HF) radars deployed in the northern and southern hemispheres to measure ionospheric plasma circulation. Each partner institution secures funding and manages operations for their own facilities. The continued availability of SuperDARN data depends on the proper acknowledgment of data by its users. Guidelines for data acknowledgment are as follows: When data from an individual radar or radars are used, users must contact the principal investigator(s) of those radar(s) to obtain the appropriate acknowledgement information and to offer collaboration, where appropriate. Contact information is available in the README file for this collection. For all usage of SuperDARN data, users are asked to include the following standard acknowledgment text: “The authors acknowledge the use of SuperDARN data. SuperDARN is a collection of radars funded by national scientific funding agencies of Australia, Canada, China, France, Italy, Japan, Norway, South Africa, United Kingdom and the United States of America.” While SuperDARN has an open data use policy, i.e., prior permission to access and analyse the data is not required, the data user is strongly encouraged to establish early contact with any Principal Investigator whose data are involved in the project to discuss the intended usage and collaboration. Data can be subject to limitations that are not immediately evident to users. In addition, some data are embargoed for use by designated Principal Investigators for a period of one year. SuperDARN and the organizations that contributed data must be acknowledged in all reports and publications that use SuperDARN data. The SuperDARN Executive Council must be notified before data are redistributed through another database. The data are not to be used for commercial purposes. If you have any questions about appropriate use of these data, contact any SuperDARN Principal Investigator.SuperDARN流星风数据：*.m.* 代表经向（正方向为极向），*.z.* 代表纬向（正方向为东向）；X/Y坐标采用雷达坐标系，多数用户可忽略此说明。本数据集由美国国家科学基金会（National Science Foundation, NSF）编号#1934973的合作研究项目“超双极光雷达网络（Super Dual Auroral Radar Network, SuperDARN）运行、研究与社区支持”资助。 SuperDARN是一项国际合作项目，其运行部署于南北半球的高频（HF）雷达可用于探测电离层等离子体环流。各合作机构负责为本机构的雷达设施筹措经费并管理其运行。 SuperDARN数据的持续可获取性，依赖于用户对数据来源的合理致谢。数据致谢规范如下： 1. 若使用单台或多台雷达的数据，用户需联系对应雷达的首席研究员（Principal Investigator, PI），获取恰当的致谢文本，并视情况提出合作意向。本数据集的自述文件（README）中已提供相关联系方式。 2. 无论以何种形式使用SuperDARN数据，用户均需包含以下标准致谢语句：“作者感谢对SuperDARN数据的使用。SuperDARN是由澳大利亚、加拿大、中国、法国、意大利、日本、挪威、南非、英国及美国的国家科学资助机构支持的雷达组网项目。” 尽管SuperDARN实行开放数据政策，即无需预先获得许可即可访问与分析数据，但我们强烈鼓励用户尽早与项目涉及的数据首席研究员取得联系，讨论数据使用计划与合作事宜。数据可能存在用户未即时察觉的使用限制；此外，部分数据设有为期一年的禁运期，禁运期内仅指定的首席研究员可使用该数据。 所有使用SuperDARN数据的报告与学术出版物中，均需致谢SuperDARN及提供数据的相关机构。若通过其他数据库重新分发SuperDARN数据，须提前通知SuperDARN执行委员会。本数据集不得用于商业用途。若您对数据的合理使用存在任何疑问，请联系任意一位SuperDARN首席研究员。
