Try these ones:
- p_g is only the greenhouse active gas pressure, which is what you want to know.
- p_ag is for anti-greenhouse pressure, so you'd use the second equation for this.(not much different though)
- p_n is only the neutral gases pressure, so p=p_n+p_g/p_ag, but that doesn't matter here
- T is end temperature
- T_b is basis temperature
Important: It doesn't consider that there is a maximum of 3 for the total greenhouse factor, so some caution.
