RTE+RRTMGP

This is the repository for RTE+RRTMGP, a set of codes for computing radiative fluxes in planetary atmospheres. RTE+RRTMGP is described in a manuscript submitted Jan 17, 2019 to 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 [email protected].

Building the libraries.

1. cd build
2. Create a file Makefile.conf defining make variables FC (the Fortran 2003 compiler) and FCFLAGS (compiler flags). Alternately link to an existing file or set these as environment variables.
3. make
