Abstract:

Based on the GEOS-Chem model, the spatial-temporal characteristics and cause of surface CO₂ concentration are simulated and analyzed during 2006-2010. The results show that two high CO₂ concentration centers of northern hemisphere exist in East Asia and Northeast America. For East Asia, the maximum CO₂ concentration appears in spring, while for Northeast America, it happens in winter. And the minimum ones of these two regions apper both in summer. Moreover, the interannual growth of CO₂ volume fraction in these two regions is higher compared to other areas of northern hemisphere and the time, during which the maximum CO₂ concentration appears, changes yearly. In addition, the seasonal variation features of CO₂ concentration are different in forest, cropland and grassland with the decreasing of amplitude of seasonal cycle in turn. Furthermore, surface CO₂ concentration has a significant negative correlation with leaf area index(LAI), which means that the ecosystem, as an important carbon sink, affects the seasonal variation of surface CO₂ concentration. Two important factors (temperature and precipitation) influencing LAI also have a close relationship with surface CO₂ concentration. Correlation analysis indicates that surface CO₂ concentration has a significant negative correlation with temperature and precipitation in most part of land in northern hemisphere.
