Bending Strain Time Series for 105 Trees on Barro Colorado Island

Environmental Information Data Centre provides a 2022 dataset of bending strain measurements from 105 trees on Barro Colorado Island, Panama. Two sensors per tree recorded data at 4 Hz to estimate wind damage risk and fundamental sway frequencies. The dataset contains time-series measurements with gaps due to forest transmission issues.

Use Cases

• Estimate wind damage risk by analyzing bending strain time-series patterns from 105 instrumented trees.
• Calculate fundamental sway frequencies and track their changes over time, which relate to leaf phenology and tree water content.
• Identify and characterize short data gaps in the 4 Hz sensor recordings caused by forest transmission issues.

Strengths

• Time-series data collected at a high 4 Hz sampling rate for detailed temporal analysis.
• Measurements from 105 distinct trees provide a substantial sample for ecological study.
• Data collected for a specific purpose (wind damage risk estimation) ensures focused relevance.

Limitations

• Contains numerous short data gaps due to transmission issues, requiring gap-handling for continuous analysis.
• Limited to a single year (2022) and specific location (Barro Colorado Island), reducing generalizability.
