| Title: | Constraints imposed by the ice core data on the budgets of nitrous oxide and methane / M.A.K. Khalil, R.A. Rasmussen. |
| Author(s): | Khalil, M. A. K. Rasmussen, R. A. |
| Date: | [1989] |
| Publisher: | Cointe-Ougrée: Université de Liège, Institut d'Astrophysique |
| Abstract: | Using ice-core data, purpose was to find limits on present emissions of CH₄ and N₂O from anthropogenic and natural sources that are consistent with concentrations found 100 years ago, and are also consistent with present measured concentrations, trends and estimated lifetimes. Taking lifetime of N₂O to be 100-150 years, and of CH₄ to be 8-12 years, it was found that 10 to 30% of N₂O emissions, and 40 to 65% of CH₄ emissions, must come from human activities. Discussion, p. 409-410. |
