gCMCRT: A Monte Carlo Radiative-Transfer Forward Model
3D radiative-transfer for exoplanet atmospheres. gCMCRT: a GPU accelerated MCRT code
We develop an open source radiative-transfer code, gcmcrt, a monte-carlo forward model for general use in planetary atmosphere radiative-transfer problems.Gcmcrt is well suited for post-processing large global circulation model (gcm) modelgrids produced by members of the community and for high-resolution 3d investigations.We develop albedo, emission and transmission spectra modes for 3d and 1d input structures.We include capability to use correlated-k and high-resolution opacity tables, the latter of which can be doppler shifted inside the model.We aim to automate the post-processing pipeline, starting from direct global circulation model(gcm) output to synthetic spectra.We develop albedo, emission and transmission spectra modes for 3d and 1d input structures.We include capability to use correlated-k and high-resolution opacity tables, the latter of which can be doppler shifted inside the model.We aim to automate the post-processing pipeline, starting from direct global circulation model(gcm) output to synthetic spectra.We develop albedo, emission and transmission spectra modes for 3d and 1d input structures.We include capability to use correlated-k and high-resolution opacity tables, the latter of which can be doppler shifted inside the model.We post-process results from several gcm groups including exorad, sparc/mitgcm thor, uk met office um, exo-fms and the rauscher model.
