RTE+RRTMGP is a set of codes for computing radiative fluxes in planetary atmospheres.

RTE computes radiative fluxes given values of optical properties, source functions, and boundary conditions.

RRTMGP computes the optical properties and source functions of the gaseous atmosphere given the distribution of temperature, pressure, and gas concentrations within the atmosphere.

RTE+RRTMGP is a collaboration between the University of Colorado and Atmospheric and Environmental Research, Inc. Please contact Robert Pincus and Eli Mlawer at rrtmgp@aer.com or open an issue on this Github site.

In the Fortran 2003 interface documented here each of the italicized phrases above corresponds to a class which bundles some combination of code and data.
