Short summary
Urban green roofs (GRs) were shown to provide various ecosystem services, such as carbon sequestration. We investigate the coupling between carbon, water, and energy exchange of a large, extensive GR using nine years of eddy-covariance data to determine their role in shaping the net ecosystem exchange. The GR acted as a moderate carbon sink with distinct annual and seasonal variation influenced by the coupled exchange processes. This highlights the importance of long-term flux monitoring.
