N this steadystate radiative transfer modeling, the time step is only for the iteration computation and there isn’t any trouble to map the non-dimensional variables to variables’ units. Since the LBM-RT in this paper is actually a steady-state problem, only conversions are required between physical length and non-dimensional length, and also the scattering and absorption coefficients and non-dimensional Ritanserin 5-HT Receptor parameters a and b (a scattering albedo, b optical depth) could be transformed making use of Equations (ten) and (11). The radiation intensity is usually converted to a physical unit by multiplying the value of incoming boundary intensity having a physical unit.Atmosphere 2021, 12,13 of4. Discussion and Conclusions This paper reported a newly developed radiative transfer model employing the lattice Boltzmann method, RT-LBM, for applications in atmospheric environments. The test benefits indicated the new RT-LBM has reasonably correct final results compared with traditional MC models. The model takes benefit with the LBM algorithms of collision and streaming to accelerate the computation speed. The implementation of RT-LBM employing the GPU has realized a computation speed-up of 120 times faster than a CPU implementation for a very big domain. RT-LBM also had a ten times speed-up over the MC model to get a same radiative case on the exact same CPU, which makes a total of a 406 times speed-up for RT-LBM on a GPU over the MC model on a CPU. The atmospheric atmosphere is a complicated composite of a lot of various gases, aerosols, and hydrometers, and the composition is extremely dynamic. The optical parameters are frequently very distinct for diverse wavelengths of radiation. In atmospheric radiative transfer modeling, numerous runs for various spectral lengths with distinctive optical parameters have to be produced to finish the complete radiative energy transfer domain. Due to the fact radiative modeling is computationally intensive, the newly developed RT-LBM delivers advantages. Nonetheless, numerous research areas, including complex boundary specification, anisotropic scattering by substantial aerosols, and optical parameters specification, have to be carried out to recognize the prospective of this new system for precise applications. Some applications, like for solar energy, are feasible with RT-LBM working with broadband optical parameters to lower the complexity. Within this case, solar radiation could be divided into two spectral bands, shortwave and longwave. Two different sets of bulk optical parameters might be made use of for solar shortwave radiation and longwave radiation in the ground surface.Author Contributions: Conceptualization, RT-LBM, Y.W.; methodology, Y.W.; computer Sodium citrate dihydrate Protocol software, J.D., Y.W. and X.Z.; formal evaluation, Y.W.; MC modeling, X.Z.
