 Cloud-J is a multi-scattering eight-stream radiative transfer model for solar radiation based on Fast-J. It was originally developed by Michael J. Prather (UCI). For information about the origins and history of Cloud-J and its predecessor Fast-J please see the [history document](https://github.com/geoschem/cloud-j/blob/main/docs/History_of_Fast-J_photolysis_code.md) in the docs subdirectory of this repository.
