Main Findings
- 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.
