Hi,

Is it possible to change the concentration of methane and nitrous oxide in CAM, I found the formula in the scientific description for methane so I assume it is. I have not used the model yet however I am told changing co2 is a simple matter of changing one value in the namelist. Is CH4VMR and CO2VMR simply the concentration of methane and co2 in the atmosphere respectively (looking at the default values it looks like it)? I notice Nitrous oxide is not in the namelist, is this not implemented in CAM3?

Cheers in advance,
