The SASKTRAN Radiative Transfer Framework¶
The SASKTRAN radiative transfer framework is a radiative transfer tool developed at the University of Saskatchewan.
Originally designed for use with the OSIRIS instrument (https://research-groups.usask.ca/osiris/) it has since
evolved to be applicable to a large variety of applications. SASKTRAN is a full framework and not just a radiative
transfer model, as such it contains databases or interfaces to standard climatologies and species optical properties.
It also contains multiple methods to solve the radiative transfer equation that we call engines, each one of which has a
specific domain that it is applicable to. The primary engines are
SASKTRAN-HR which is a fully spherical
scattering model, and
SASKTRAN-DO which is a discrete ordinates model suitable for nadir viewing applications,
SASKTRAN_TIR which is a spherical thermal infrared model suitable in the absence of scattering.
The SASKTRAN code is open-source and is in active development at https://github.com/usask-arg/sasktran
SASKTRAN is made available under the MIT license restricted for academic and educational use, for commercial use please contact the package authors. Commerical level support may also be available for specific applications.
