Lanzhou Lily Phenology and Climate Data from Northwest China, 1995-2024

1995–2024 continuous field observations of Lanzhou lily phenology and daily meteorological records from a temperate semi-arid region in Northwest China. The dataset quantifies trends in four phenological metrics and identifies phase-specific climatic sensitivity windows. It was authored by Xiaohui Ma and shared under a CC-BY-4.0 license.

Use Cases

• Modeling the impact of temperature on plant emergence and bloom timing based on the identified sensitivity windows.
• Analyzing the opposing effects of temperature and sunshine duration on full bloom and senescence phases.
• Forecasting growing season length for perennial bulb crops under climate change scenarios.
• Quantifying long-term phenological shifts (e.g., days advanced per decade) in a key agricultural region.

Strengths

• 30-year continuous observation period (1995–2024).
• Includes four specific phenological metrics: emergence, full bloom, shoot senescence, and growing season length.
• Quantifies trends with specific rates (e.g., 1.69 days per decade advance for shoot senescence).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (474.8 KB), indicating a limited scope.
