Eddy covariance observations of CO2, latent heat, and sensible heat fluxes at the Spiekeroog Coastal Observatory@en

Observations of vertical fluxes of CO2, latent heat, and sensible heat were made at the Spiekeroog Coastal Observatory in the German Wadden Sea between 1.1.2021 and 28.12.2022. Measurements were made with an eddy covariance (EC) system consisting of a sonic anemometer (Gill Windmaster) and infrared gas analyzer (Li-7200), and processed in EddyPro according to standard methods. This dataset was gathered for the purpose of investigating the drivers of air-sea fluxes, but includes observations of fluxes influenced by the nearby Spiekeroog island, which may also be of interest. Identification of land vs sea fluxes can be made with a flux footprint analysis and by screening according to wind direction.2021年1月1日至2022年12月28日，研究人员于德国瓦登海施皮克奥格海岸观测站开展了二氧化碳（CO₂）、潜热与感热垂直通量的观测工作。本次观测采用由超声风速仪（sonic anemometer，Gill Windmaster）与红外气体分析仪（infrared gas analyzer，Li-7200）组成的涡度协方差（eddy covariance, EC）系统，并通过EddyPro软件遵循标准方法完成数据处理。本数据集的采集目的为探究海气通量的驱动因子，但其观测得到的通量同时受到邻近施皮克奥格岛的影响，该部分观测数据同样具备研究价值。可通过通量足迹分析以及依据风向的筛选操作，实现陆地通量与海洋通量的区分。
