CHARACTERIZATION OF NITROUS OXIDE EMISSION SOURCES
Peer, R., E. Epner, AND R. Billings. CHARACTERIZATION OF NITROUS OXIDE EMISSION SOURCES. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/R-95/105 (NTIS PB95-246252), 1995.
The report presents a global inventory of nitrous oxide (N2O) based on reevaluation of previous estimates and additions of previously uninventoried source categories. (NOTE: N2O is both a greenhouse gas and a precursor of nitric oxide (NO) which destroys stratospheric ozone.) The best estimate of anthropogenic N2O is 5.7 Tg/yr, which is still much lower than natural source emissions. Much uncertainty remains about estimates for many source categories. Inadequate data are available for some categories, while others are limited by a lack of reliable functional models of factors affecting emission rates.
