pyRT_DISORT is a Python package that creates inputs to the the DISORT core radiative transfer algorithm. It is now a companion repository to pyDISORT (pyDISORT contains the code to create the binarized version of DISORT whereas pyRT_DISORT is a project to simply create many of the arrays and constants required by DISORT).
The best way to get started with pyRT_DISORT is to check out the documentation.
