SMART-G Monte Carlo GPU Radiative Transfer
SMART-G (Speed-Up Monte Carlo Advanced Radiative Transfer using GPU) is an advanced radiative transfer code. Initially co-developed by HYGEOS for CNES
to simulate how the light propagates in the atmosphere and ocean, SMART-G is now continuously upgraded by HYGEOS. Examples are given below.
Monte Carlo solver
Accounts for light polarization
Works in plane parallel or spherical geometry
GPU accelerated using the CUDA framework (massively parallel processing)
Accounts for reflection/transmission by a wind-roughened sea surface, including wave shadowing effects
Accounts for adjacency effects
Coded in python + pycuda
One poster presented at the IOCS conference in 2015 on few possible applications with SMART-G.
Another poster on SMART-G computing time improvement by implementing the ALIS scheme.
New developments in radiative transfer were also performed by HYGEOS for another code called ARTDECO.
Poster presented at IRS in 2016.
