Thermal radiation is an important mode of heat transfer. Accurate modeling of radiative transfer requires accurate data and models for spectral properties as well as good radiation solvers. This repository holds several such property data, tools, and solvers.
Many of the resources hosted here were developed by Michael Modest and his coworkers over several years with support from various funding agencies. This repository is now maintained and continuously updated by Dr. Somesh Roy.
