Franks Model CO2 Proxy Data: Stomatal Measurements and Isotope Inputs

435.4 MB of stomatal measurement data and leaf carbon isotope measurements accompany the R code for the Franks model CO2 proxy analysis. Hannah Morck published this dataset on figshare in April 2026 to recreate the data analysis and CO2 reconstructions from the associated paper. The data includes stomatal density, pore length, guard cell dimensions, and model input/output files.

Use Cases

• Reconstructing historical atmospheric CO2 concentrations based on stomatal measurement data.
• Analyzing the relationship between stomatal morphology and CO2 levels using stomatal density and pore length.
• Comparing CO2 proxy model outputs based on leaf carbon isotope measurements from the TRY database.
• Visualizing stomatal measurement trends and CO2 estimates using the provided R code.

Strengths

• Dataset size is 435.4 MB, indicating a substantial collection of measurement data and code.
• Includes both raw stomatal measurement data (density, pore length, guard cell dimensions) and processed Franks model input/output.
• Associated R code is provided for full reproducibility of the analysis and plotting from the paper.
• License is CC-BY-4.0, allowing for open sharing and reuse.

Limitations

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