Scattering

Mie theory, Greek-coefficient phase matrices, NAI2 / PCW Fourier decomposition, vector δ-m truncation.

Absorption

HITRAN line-by-line cross sections with Voigt, Doppler, and Lorentz line shapes; lookup-table interpolation for hot loops.

Radiative Transfer

Adding-doubling matrix operator method, polarized solver, analytic Jacobians, Raman / Cabannes inelastic path, GPU-ready.

Public Modules ​

  • CoreRT — adding-doubling solver, model types, optical-property assembly, surface coupling, Jacobian kernels.

  • IO — YAML, TOML, Dict, NetCDF, and GEOS-Chem inputs.

  • Absorption — HITRAN line-by-line and lookup-table gas absorption.

  • Scattering — Mie calculations, phase functions, Greek coefficients, truncation inputs.

  • InelasticScattering — Raman / Cabannes mode types and optical-property helpers.

  • Aerosols — TOMAS-15 and two-moment aerosol input support. API still being stabilized.

  • SolarModel — solar / stellar spectra and transmission helpers.
