In-situ measurements of urban atmospheric water isotopes (δv) at different elevations produce reliable high-resolution data. Urban atmospheric vapour is influenced by varying drivers depending on the type of green space. δv above grassland and tree stands was similar at 10 m height, but near-surface δv above indicated higher evaporation and vapour enrichment over grass. We detected occasional dis-equilibrium between vapour and precipitation isotopes.
