v1.0.2 — AGU Advances Revision Version

This release corresponds to the revised version of the code submitted with manuscript #2026AV002398 to AGU Advances (in revision). Key updates: x-axis converted to relative distance (km) in all cross-section plots; citation updated to reflect revision status.

v1.0.1 — AGU Advances Submission Version (Zenodo Archive)

This release corresponds to the version of the code used for the submission of:

Moshtaghian et al. (2026),
"Frequency-domain Airborne Electromagnetic Imaging of Permafrost Reveals Heterogeneity and Drivers of Permafrost Change in the Discontinuous Permafrost Zone of Northwestern Canada",
submitted to AGU Advances.

This version is archived to ensure full computational reproducibility of all figures and results presented in the manuscript.

Core components included:

• 1D frequency-domain AEM inversion using SimPEG
• Depth of Investigation (Oldenburg & Li, 1999; Christiansen & Auken, 2012)
• Center-based gradient permafrost base detection
• Permafrost Base Transition Zone (PBTZ) estimation
• Reproducible plotting and RMS misfit diagnostics

This release is intended as the frozen submission version. Subsequent minor updates (e.g., citation formatting after publication) will not alter this archived snapshot.
