Description
This repository gathers grids of aerosols extinction extinction, scattering extinction and asymmetry parameters for use in exoplanet atmospheric retrieval (or proto-planetary disks). The grids spans particle radii from 1 nanometer to 30 microns. They are designed and validated for JWST high information content datasets, see Voyer & Cangeat (2026). These grids are meant to be used easely in any framework but already compatible with the TauREx retrieval code through the new plugin TauREx-PCQ (https://github.com/groningen-exoatmospheres/taurex-PCQ/). The following species are already available :
-Mg2SiO4 amorph glass
-MgSiO3 amorph glass
-MgSiO3 amorph sol-gel
-SiO2 alpha
-SiO2 amorph
-SiO
-Titan tholins
If you use any of this data in your research please cite Voyer & Changeat (2026). For any inquiries please contact mael.voyer@u-paris.fr.
