Clough, 1997: Radiative transfer for inhomogeneous atmosphere: RRTM, a validated correlated-k model for the longwave.
Skin firmness, the primary efficacy variable, was assessed at the start of the trial and after treatment for 28 days using a devise to measure shear wave propagation in the skin, Reviscometer RVM 600[R] (Courage + Khazaka Electronic, Cologne, Germany), for recording Resonance Running Time, RRTM, expressed in arbitrary time units.
The model configuration was the same as the highly tested University of Washington real-time WRF configuration, using WRF-ARW V3.7.1, Yonsei University (YSU) planetary boundary layer (PBL), Thompson microphysics, RRTM for GCMs (RRTMG) radiation, and the Noah land surface model with multiple parameterization options (Noah-MP), but with one exception: the number of vertical levels was increased from 38 to 75.
The radiation model was the RRTMG (rapid radiative transfer model for general circulations models) [35], which is a relatively recent version of the RRTM (rapid radiative transfer model) [36], with a better representation of cloudiness, unresolved by the mesh of the model.

For type RRTM there has not been any improvement observed, and given the resource consumption, it should be considered whether or not to study its use depending on the specific application desired.
The transaction also includes the intellectual property rights related to the programme as well as Rolls-Royce's 50% stake in the Rolls-Royce-Turbomeca (RRTM) joint venture.
