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.

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.
