摘要

生物甲烷的碳源主要来自于活性碳库。碳通过生物源性循环转化为甲烷意味着生物源性甲烷导致的全球变暖(GW)继承了co2的GW。为了准确、真实地评估生物甲烷的全球变暖潜能值及其对全球变暖的贡献，应从生物甲烷的瞬时辐射强迫中减去co2的瞬时辐射强迫。在此基础上提出的修正将使生物甲烷的全球升温潜能值降低5%。拟议的修正意义重大，因为全球80%的甲烷排放涉及属于活性碳库的生物圈碳。DOI: 10.1034 / j.1600 0889.1999.t01 - 2 - 00003. x

Global warming potential of biogenic methane

The source of carbon in biogenic methane comes from the active carbon pool. Transformation of carbon into methane, through biogenic cycling of carbon implies that the global warming (GW) contributed by biogenic methane inherits the GW of CO 2 . For a precise and realistic assessment of GWP of biogenic methane and its' contribution to GW, the instantaneous radiative forcing of CO 2 should be subtracted from the instantaneous radiative forcing of biogenic methane. The correction suggested on this account will decrease the GWP of biogenic methane by 5%. The proposed correction is significant, since 80% of the global emission of methane involve biospheric carbon belonging to the active carbon pool. DOI: 10.1034/j.1600-0889.1999.t01-2-00003.x

期刊介绍： Tellus B: Chemical and Physical Meteorology along with its sister journal Tellus A: Dynamic Meteorology and Oceanography, are the international, peer-reviewed journals of the International Meteorological Institute in Stockholm, an independent non-for-profit body integrated into the Department of Meteorology at the Faculty of Sciences of Stockholm University, Sweden. Aiming to promote the exchange of knowledge about meteorology from across a range of scientific sub-disciplines, the two journals serve an international community of researchers, policy makers, managers, media and the general public.
