我们已经应用了一个逆模型，20年的大气二氧化碳测量，以推断海洋和大陆的区域碳平衡的年度变化。该模型表明，1980 - 1998年全球陆地碳通量的变化大约是海洋通量的两倍，热带陆地生态系统对20世纪80年代地球碳平衡的年际变化贡献最大，而北方中高纬度陆地生态系统在1990 - 1995年占主导地位，与1989-1990年相比，1992-1993年期间北美洲的碳吸收量大大增加。
We have applied an inverse model to 20 years of atmospheric carbon dioxide measurements to infer yearly changes in the regional carbon balance of oceans and continents. The model indicates that global terrestrial carbon fluxes were approximately twice as variable as ocean fluxes between 1980 and 1998, Tropical Land ecosystems contributed most of the interannual changes in Earth's carbon balance over the 1980s, whereas northern mid- and high-latitude Land ecosystems dominated from 1990 to 1995, Strongly enhanced uptake of carbon was found over North America during the 1992-1993 period compared to 1989-1990.
