Grassland Carbon Flux Under Climate Treatments

Kathiravan Meeran from Universität Innsbruck provides data on ecosystem CO2 fluxes, soil respiration, and 13CO2 dynamics. The dataset contains measurements from a grassland experiment during summer 2017, featuring drought, elevated CO2, and warming treatments. It includes three CSV files for ecosystem fluxes, excess 13C, and time-series dynamics, accompanied by R scripts for analysis and visualization.

Use Cases

• Analyzing the impact of drought, warming, and elevated CO2 on grassland carbon fluxes.
• Modeling relationships between soil respiration and environmental drivers like soil water content and temperature.
• Tracing 13C isotope allocation in plants and soil following pulse labeling.
• Comparing gross primary productivity, ecosystem respiration, and net ecosystem productivity under experimental treatments.

Strengths

• Includes experimental data from three distinct climate treatments: drought, elevated CO2, and warming.
• Provides accompanying R code for data explanation, plotting, and time-series regression analysis.
• Contains data on multiple carbon cycle components: ecosystem fluxes, soil-respired CO2, and 13CO2 isotope dynamics.

Limitations

• Key metadata such as row count, column names, and specific file sizes are not provided across all sources.
• The temporal coverage is limited to a single summer season (2017).
• Documentation relies on R scripts; a formal data dictionary or detailed metadata file is not mentioned.
