Introduction

Resources for newcomers to the group and to HF ray-tracing / ionospheric model validation.

Table of Contents

Software

  • The group’s 3D HF ray-tracing engine is implemented natively in Python, based on the Jones & Stephenson ray-tracing formulation, independent of PHaRLAP’s proprietary core. It is under active development; see src/README.md for its current status.
  • PyLap — the team’s earlier open-source 2D Python wrapper for PHaRLAP’s ray-tracing engine. Separate from the 3D engine above; kept here as related prior work.
  • HamSCI GitHub — where this project’s ray-tracing, model validation, and analysis code will be posted as it matures.
  • HF-START — a related near real-time public HF 3D ray-tracing service developed by the PI.
