Global Plant Nitrogen Availability Data Linked to Precipitation and CO2

18.0 MB of source data underpinning research on the joint influence of precipitation and atmospheric CO2 on plant nitrogen availability worldwide. The dataset, created by Songbo Tang and shared under a CC-BY-4.0 license, was last updated on May 1, 2026. Its CSV format suggests a tabular structure likely containing environmental and biological measurements.

Use Cases

• Modeling global patterns of plant nitrogen availability based on the described link to precipitation and CO2.
• Analyzing the interaction between climate variables and nutrient cycles based on the dataset's core research theme.
• Validating or extending findings on long-term environmental controls of terrestrial ecosystems.
• Teaching concepts in global ecology and climate change impacts using real-world source data.

Strengths

• Data is directly linked to published research on a specific ecological mechanism.
• Shared under a permissive CC-BY-4.0 license, facilitating reuse.
• File size of 18.0 MB indicates a manageable download and processing scale.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
