An overview is given of 50-year Cabauw observations and research on the structure and dynamics of the atmospheric boundary layer. It is shown that over time this research site with its 200-m meteorological tower has grown into an atmospheric observatory with a comprehensive observational program encompassing almost all aspects of the atmospheric column including its boundary conditions. This is accomplished by the Cabauw Experimental Site for Atmospheric Research (CESAR) a consortium of research institutes. CESAR plays an important role in the educational programs of the CESAR universities. The current boundary-layer observational program is described in detail, and other parts of the CESAR observational program discussed more briefly. Due to an open data policy the CESAR datasets are used by researchers all over the world. Examples are given of the use of the long time series for model evaluation, satellite validation, and process studies. The role of tall towers is discussed in relation to the development of more and better ground-based remote sensing techniques. CESAR is now incorporated into the Ruisdael observatory, the large-scale atmospheric research infrastructure in the Netherlands. With Ruisdael the embedding of the Dutch atmospheric community in national policy landscape, and in the European atmospheric research infrastructures is assured for the coming decade.

Cabauw 大气边界层研究五十年服务于天气、空气质量和气候

概述了 50 年 Cabauw 对大气边界层结构和动力学的观测和研究。结果表明，随着时间的推移，这个拥有 200 米气象塔的研究站点已经发展成为一个大气观测站，其综合观测计划涵盖了大气柱的几乎所有方面，包括其边界条件。这是由研究机构联盟的 Cabauw 大气研究实验站 (CESAR) 完成的。CESAR 在 CESAR 大学的教育计划中发挥着重要作用。详细描述了当前的边界层观测计划，更简要地讨论了 CESAR 观测计划的其他部分。由于开放数据政策，CESAR 数据集被世界各地的研究人员使用。给出了使用长时间序列进行模型评估、卫星验证和过程研究的示例。高塔的作用与开发更多更好的地面遥感技术有关。CESAR 现在并入荷兰的大型大气研究基础设施 Ruisdael 天文台。有了 Ruisdael，荷兰大气界将在未来十年内融入国家政策格局和欧洲大气研究基础设施。荷兰的大型大气研究基础设施。有了 Ruisdael，荷兰大气界将在未来十年内融入国家政策格局和欧洲大气研究基础设施。荷兰的大型大气研究基础设施。有了 Ruisdael，荷兰大气界将在未来十年内融入国家政策格局和欧洲大气研究基础设施。
