Global Leaf Photosynthetic Rates and Nutrient Traits for 325 Species

325 species and treatment combinations provide data on leaf photosynthetic rates (Vcmax, Jmax), nitrogen (N), phosphorus (P), and specific leaf area (SLA). This global dataset was compiled by NASA from a literature review of experimental and ambient field conditions. It includes both original published values and estimates standardized to a common temperature.

Use Cases

• Modeling global carbon fluxes based on photosynthetic parameters Vcmax and Jmax
• Exploring relationships between leaf photosynthetic capacity and nutrient content (N, P)
• Investigating trait correlations between specific leaf area (SLA) and photosynthetic rates
• Calibrating Earth system models with standardized leaf trait data

Strengths

• Compiled from a literature review, providing a synthesized global view
• Includes 325 species and treatment combinations
• Reports both original and temperature-standardized values for Vcmax and Jmax

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
