Tropical Forest Tree Leaf Water Potential Time Series from Western Ghats

Sirsi, Western Ghats, India contains time-series of pre-dawn and mid-day leaf water potentials for 10 tree species. Measurements were taken every three months over one year, from 2020 to 2021, to assess eco-physiological limits of functioning under dry conditions.

Use Cases

• Model tree safety margins by analyzing time-series trends in pre-dawn and mid-day leaf water potential across 10 species.
• Correlate seasonal leaf water potential measurements with hydraulic conductance vulnerability curves to define safe operating spaces.
• Assess drought response by comparing pre-dawn and mid-day water potential values for tropical forest tree species.

Strengths

• Time-series data collected every three months over a full year.
• Covers 10 distinct tropical tree species.
• Includes both pre-dawn and mid-day leaf water potential measurements.

Limitations

• Sample size is limited to one forest site in Sirsi, restricting geographic generalizability.
• Data collection frequency is quarterly, which may miss finer temporal dynamics.
