Buhler Piqueux 2021: Mars CO2 Inventory Model Outputs for Figures 3-6

Mars CO2 inventory model outputs from Buhler and Piqueux (2021), published in the Journal of Geophysical Research. The data includes ten tables with model results for atmosphere mass, cap mass, and adsorbed CO2 mass as functions of obliquity and regolith thickness, plus Markov Chain Monte Carlo simulation chains. All values were calculated assuming specific regolith thermal conductivity and albedo.

Use Cases

• Analyzing the relationship between Martian obliquity and CO2 distribution based on the provided 2D arrays.
• Validating or comparing Mars climate models using the published model output solutions for atmosphere, cap, and adsorbed CO2 mass.
• Investigating parameter sensitivity using the MCMC simulation chains for regolith thermal conductivity, thickness, and specific surface area.
• Reproducing the figures from the original JGR paper using the provided data tables.

Strengths

• Data is directly linked to a peer-reviewed publication in the Journal of Geophysical Research (2021).
• Model outputs are provided for seven different regolith thickness values and 91 obliquity values (0-90 degrees).
• Includes a large MCMC chain table with 10 million steps for three key parameters.
• Explicitly states the fixed model assumptions (regolith thermal conductivity = 1.0 W m⁻¹ K⁻¹, albedo = 0.25).

Limitations

• Column-level documentation is absent; field semantics must be inferred from the description after download.
• Row count for the primary data tables is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
