Abstract:
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.
