This page evaluates the RRTMGP gas optics scheme (v1801204), designed for weather and climate applications. The comparisons below use the 50 profiles of the "Evaluation-1" CKDMIP dataset. The reference calculations were performed using LBLRTM to generate the high resolution absorption spectra and the CKDMIP software to perform the radiative transfer. See also the results for the later version 1.5 of RRTMGP (including full and reduced spectral resolution), as well as earlier RRTMG gas optics scheme, and also those from a Neural Network approximation to RRTMGP.
