The process of the official document CLUBB written by Larson in 2019 is as follows: Step 1 Advance higher-order moments one time step. CLUBB prognoses several subgrid turbulent fluxes, plus several variances and covariances, and finally one third-order moment, the third-order moment of the vertical velocity disturbance. Step 2 Given the updated higher-order moments, diagnose the subgrid PDF. But in clubb/advance_clubb_core_module.F90 subgrid turbulent fluxes plus several variances and covariances, and finally one third-order moment. It seems that these quantities are not calculated by CLUBB but output by other modules? Could someone tell me why it is like this
