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.
