The N2O Module

Nitrous oxide or laughing gas (N₂O) is produced both naturally and artificially. This greenhouse gas is produced and consumed by biological processes in soil and water and is removed from the atmosphere much more slowly than methane. The yearly growth in the N₂O emission trend varied from 0.1% at the beginning of this century to 1.3% in the last 10 years. The current average concentration of N₂O is about 0.308 ppm and is increasing at about 0.2 to 0.3 percent a year (0.18- -0.26% according to Lyon et al., 1989). For N₂O a simple one-box emissions and concentration module has been implemented.
