SMART-G (Speed-up Monte Carlo Advanced Radiative Transfer Code using GPU) is a radiative transfer code using a Monte-Carlo technique to simulate the propagation of the polarized light in the atmosphere and/or ocean, and using GPU acceleration.

The smartg dependencies can be installed on anaconda with the following command:
# create a new environment and activate it (optional but recommended) conda create -n smartg -c conda-forge mamba conda activate smartg # install all SMART-G dependencies mamba env update -f environment.yml
The auxiliary data can be downloaded with the following command:
$ make auxdata_all
Examples are provided in the sample notebooks.
jupyter notebook has nice possibilities for interactive development and visualization, in particular if you are using a remote cuda computer. Sample notebooks are provided in the folder notebooks.
Example of pytest.ini file:
[pytest] addopts= --html=test_reportv1.html --self-contained-html -s -v
Run the command pytest tests/test_cuda.py tests/test_profile.py tests/test_smartg.py to check that SMART-G is correctly running.

The use of GPUs before 10xx series (Pascal) is depracated as of SMART-G 1.0.0
This software is available under the SMART-G licence v1.0, available in the LICENCE.TXT file.
