This is a C++ implementation (including a Monte Carlo ray tracer) of the Radiative Transfer for Energetics (RTE) and Rapid Radiative Transfer Model for GCM applications Parallel (RRTMGP).
The original code is found at https://github.com/earth-system-radiation/rte-rrtmgp.

In order to check out the code including the rte-rrtmgp
submodule, use:
git clone --recurse-submodules https://github.com/earth-system-radiation/rte-rrtmgp-cpp
In case you had already checked out the repository, use:
git submodule update --init
For building from source, create a build directory, for instance build
.
From build
, trigger cmake .. -DSYST=config_file
, where config_file
should be replaced by one of the configuration files in the config
folder, for instance -DSYST=macbook_brew
.
Building the source creates an executable test_rte_rrtmgp
.
Three test cases are provided in directories rfmip
, allsky
, and rcemip
.
In order to run those cases follow the instructions in the README.md
of those respective directories.
In general, in order to run a test case, make sure the following files are present in the
directory from which test_rte_rrtmgp
is triggered:
- Input file
rte_rrtmgp_input.nc
with atmospheric profiles of pressure, temperature, and gases. - Long wave coefficients file from original RTE+RRTMGP repository (in
rrtmgp/data
) ascoefficients_lw.nc
- Short wave coefficients file from original RTE+RRTMGP repository (in
rrtmgp/data
) ascoefficients_sw.nc
- Long wave cloud optics coefficients file from original RTE+RRTMGP repository (in
rrtmgp-data
) ascloud_coefficients_lw.nc
- Short wave cloud optics coefficients file from original RTE+RRTMGP repository (in
rrtmgp-data
) ascloud_coefficients_sw.nc
