From June 2018 to August 2020, 66 event-based precipitation samples were collected at Guyuan Station in China. The dataset contains stable isotopes of hydrogen and oxygen (δ²H and δ¹⁸O) and deuterium excess (d-excess) compositions derived from laboratory analysis. It was authored by Fen Zhang and shared under a CC-BY-4.0 license.
Use Cases
- Modeling local meteoric water lines based on stable isotope ratios.
- Investigating moisture sources and atmospheric processes using deuterium excess values.
- Calibrating or validating regional hydrological models with event-based precipitation chemistry.
Strengths
- 66 event-based samples provide discrete precipitation chemistry data.
- Covers a specific two-year period from June 2018 to August 2020.
- Includes three key geochemical measurements: δ²H, δ¹⁸O, and d-excess.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
