Leaf Thermoregulation Traits Across Three Elevations in Colombian Andes, 2024-2025

29 tree species were measured across three common garden plantations with mean annual temperatures of 13.7 °C, 22.1 °C, and 25.5 °C in the Colombian Andes. The dataset includes high-resolution leaf thermocouple data, optical properties, thermotolerance metrics like T50 and PSII efficiency, and leaf angle measurements. Data were collected by the Environmental Information Data Centre during campaigns in January-February 2024 and April 2025.

Use Cases

• Modeling leaf temperature regulation based on high-resolution thermocouple and PAR data.
• Assessing species thermotolerance by analyzing T50 and PSII efficiency metrics across temperature gradients.
• Studying leaf energy balance using reflectance, transmittance, and absorptance optical properties.
• Investigating leaf posture and orientation effects via pitch, roll, azimuth, and vertical angle measurements.
• Correlating minimum leaf conductance (gmin) with environmental stress across different mean annual temperatures.

Strengths

• Includes data from 15 species at 13.7°C, 10 species at 22.1°C, and 4 species at 25.5°C sites.
• Contains high-resolution time-series data at 1-minute (thermocouple, PAR) and 10-minute (leaf temperature, humidity, air temperature) intervals.
• Measures a wide range of functional traits including thermotolerance, optics, angles, and conductance.

Limitations

• Sampling at the warmest site (25.5°C) was limited to a subset of measurements.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
