Mixing ratio in ppm.  

mixing_ratio species value

 
species can be one of the following:

O2

The mixing ratio of O2 in ppm. Scale the profile so that the mixing ratio at the user-defined altitude assumes the specified value.

H2O

The mixing ratio of H2O in ppm. Scale the profile so that the mixing ratio at the user-define altitude assumes the specified value.

CO2

The mixing ratio of CO2 in ppm. The profile is scaled so that the mixing ratio at the user-defined altitude assumes the specified value.

NO2
CH4

The mixing ratio of CH4 in ppm (default: 1.6 ppm).

N2O

The mixing ratio of N2O in ppm (default: 0.28 ppm).

F11

The mixing ratio of F11 in ppm (default: 0.000268 ppm).

F12

The mixing ratio of F12 in ppm (default: 0.000503 ppm).

F22

The mixing ratio of F22 in ppm (default: 0.000105 ppm).
