BackForward Variable: N2O mole fraction (BG)

Definition
Full name N2O mole fraction (BG)
Definition 3D field of amount of  background (BG) N2O (Nitrous Oxide, expressed in moles) divided by the total amount of all constituents in dry air (also expressed in moles)
Measuring Units ppb Uncertainty Units ppb
Horizontal Res Units km Vertical Res Units km
Stability Units ppb (Stability /decade)
