Archived snapshot of the RRTMG_SW and RRTMG_LW offline radiative transfer models developed at AER

This Zenodo record provides a frozen snapshot of the RRTMG shortwave (RRTMG_SW) and longwave (RRTMG_LW) radiative transfer models, developed and maintained by Atmospheric and Environmental Research (AER).

The snapshot corresponds to the RRTMG model used in the manuscript "Enhanced radiative cooling by large aerosol particles from wildfire-driven thunderstorms" by Li et al., 2025,  and is archived here solely to ensure long-term reproducibility of the results reported therein.
