Goethite/Hematite Ratio Spectral Model Data for Earth and Mars, Including Gale Crater

Processed numerical data supporting a novel spectral model for quantifying iron oxide ratios in soils and sediments. The 28.3 KB dataset includes summary tables for synthetic standards, Hainan soil samples, and spectral parameters from ChemCam and CheMin instruments. Author Pang compiled derived metrics and comparison tables from the USGS and RELAB databases for the associated research article.

Use Cases

• Validate spectral models for iron oxide quantification based on derived spectral metrics.
• Compare mineralogical data from different instruments (e.g., ChemCam, CheMin) based on the provided comparison tables.
• Benchmark soil sample spectral signatures against synthetic standards included in the dataset.
• Apply the spectral model to new Martian or terrestrial spectral data based on the compiled parameter values.

Strengths

• Data is directly linked to a peer-reviewed research article describing a novel spectral model.
• Includes processed data from authoritative spectral databases (USGS and RELAB).
• File size is 28.3 KB, ensuring quick download and inspection.

Limitations

• Row count and column-level documentation are unknown; field semantics must be inferred after download.
• The dataset is small (28.3 KB), indicating limited scope and sample size.
• Original raw data are stored in third-party repositories, requiring separate access.
