This is the repository for RTE+RRTMGP, a set of codes for computing radiative fluxes in planetary atmospheres. RTE+RRTMGP is described in a paper in Journal of Advances in Modeling Earth Systems.
RRTMGP uses a k-distribution to provide an optical description (absorption and possibly Rayleigh optical depth) of the gaseous atmosphere, along with the relevant source functions, on a pre-determined spectral grid given temperatures, pressures, and gas concentration. The k-distribution currently distributed with this package is applicable to the Earth's atmosphere under present-day, pre-industrial, and 4xCO2 conditions.
RTE computes fluxes given spectrally-resolved optical descriptions and source functions. The fluxes are normally summarized or reduced via a user extensible class.
Example programs and documenation are evolving - please see examples/ in the repo and Wiki on the project's Github page. Suggestions are welcome. Meanwhile for questions please contact Robert Pincus and Eli Mlawer at rrtmgp@aer.com.

Two examples are provided, one for clear skies and one including clouds. See the README file and codes in each directory for further information.
