Nitrous oxide: trends and global mass balance over the last 3000 years / M.A.K. Khalil, R.A. Rasmussen.
Title: | Nitrous oxide: trends and global mass balance over the last 3000 years / M.A.K. Khalil, R.A. Rasmussen. |
Author(s): | Khalil, M. A. K. Rasmussen, R. A. |
Date: | 1988. |
Publisher: | Cambridge: International Glaciological Society |
In: | Annals of Glaciology. (1988.), Vol. 10 (1988) |
Abstract: | Ice cores from both polar regions analyzed to determine concentration of N₂O in pre-industrial and ancient atmospheres from 3000 a BP to present. Until recently, level was about 285 ppb volume; in 1984, it was 307 ppb volume. Increase mainly due to increasing use of fossil fuels. Atmospheric lifetime of N₂O is probably between 100 and 150 years. |
