Worked on enhancing gas property calculations for Mars and Venus atmospheres within the gdtk-uq/gdtk repository by updating collision integral parameters and expanding the range of modeled species. Leveraged astrophysics and thermodynamics expertise to replace legacy parameter sets with values derived from the Wright et al. collection, ensuring improved accuracy for atmospheric modeling. Developed a custom Python script to automate parameter updates, supporting reproducibility and future scalability. Emphasized data management and version control to maintain traceability and repeatability of changes. The work focused on delivering more reliable simulations for research and mission planning, demonstrating careful integration across project components.
