The downward flux by the atmosphere is the same as the real greenhouse effect. This flux is excatly the same as the sum of four energy fluxes: LW radiation absorption 155.6 + SW radiation absotpion 75.0 + Latent heating 90.8 + 24.2 = 345.6 W/m2

The model 1DAOBM-2, which I have developed, can be used to simulate the way carbon dioxide behaves in the atmosphere-ocean-biosphere system. In the former post I showed the simulation results of the yearly and cumulative CO2 flux rates. The 1DAOBM-2 can be used to simulate residence times and the future scenarios of different CO2 emission rates.
There is a real test carried out in the atmosphere nearing an end and it can be use...
