Abstract

Carbon dioxide sources for 1981–1995 are calculated using a mass-balance inversion method. Options for deriving a suitable surface constraint for the model from the available observed data are assessed. A new method, in which the longitudinal variation in the observations is accounted for, is compared to a more conventional spline fit to the data. This new constraint is applied either to the zonal mean concentration or to the concentration at all grid points. The results indicate relatively large differences between long-term mean regional sources but relatively good agreement of the interannual variations. The global and tropical sources estimated show a surprising relationship to the southern oscillation index; maximum correlation occurs for CO 2 sources leading the SOI by around 9 months.

来自质量平衡反演的CO2源:对表面约束的敏感性

用质量平衡反演方法计算了1981-1995年的二氧化碳源。评估了从现有观测数据中为模型导出合适的表面约束的各种选择。一种新的方法，其中在观测的纵向变化的考虑，比较了更传统的样条拟合的数据。这个新的约束要么应用于区域平均浓度，要么应用于所有网格点的浓度。结果表明，长期平均区域源间差异较大，但年际变化一致性较好。估计的全球和热带源与南方涛动指数有惊人的关系;在CO 2源领先SOI约9个月时，相关性最大。DOI: 10.1034 / j.1600-0889.1999.00011.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.
