Martian Gully Ice Evidence: Spectra, Thermal Properties, and HiRISE Images

Aditya Khuller's repository contains calculated spectra of snow-dust mixtures, measured spectra of ice and soil, and refractive indices of martian dust. It includes effective thermal conductivities for martian snow and ice, plus image details from HiRISE, CTX, and THEMIS instruments. The data supports analysis of exposed dusty water ice within gullies on Mars.

Use Cases

• Modeling spectral signatures of ice-dust mixtures based on the provided calculated and measured spectra.
• Analyzing thermal properties of Martian snowpacks for climate modeling based on the effective thermal conductivities.
• Studying gully formation and changes over time using the provided HiRISE, CTX, and THEMIS image details and supplementary animations.

Strengths

• Includes data from multiple cited, peer-reviewed sources (Khuller & Christensen 2020, Blaney et al. 2009, Wolff et al. 2009, Clow 1987).
• Combines spectral data, thermal property data, and high-resolution orbital image details for a multi-faceted analysis.

Limitations

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