Provenance : Amon ((isd.003))
Processing Notes : Report only for simulations (e.g., prescribed concentration pi-control run), in which the CH4 does not vary from one year to the next. Report 12 monthly values, starting with January, even if the values do not vary seasonally. When calling CMOR, identify this variable as ch4global, not ch4. If CH4 is spatially uniform, omit this field, but report Global Mean Mole Fraction of CH4 (see the table entry after the next). Are these the preferred units or should it be a unitless fraction? Should this field be reported instead on model levels? Or should we also require either the vertically integrated mole fraction (or mass?) of this species or the vertically integrated globally averaged mole fraction (or mass?)?
