TRANSCRIPT
Scheme DifferencesRRTM
RRTMg (control)-a simplified version of RRTMApproximates radiative transfer with fewer points
Like wider rectangles approximating an integral
CAM 3.0Fewer absorbing gasses and spectral bandsEmissivity and absorptivity updated every 12 hrs
Neglects dependence on T, WV, Ozone Explains lack of diurnal cycle
Not an issue when clouds are present-dominant impact calculated at every call of rad. phys
