Abstract:

The atmospheric CO2 concentration observations provide important data for global carbon cycle research and can be used to estimate the carbon source and sink of global terrestrial ecosystems and the distribution of anthropogenic carbon emissions. However, the number of high-precision ground CO2 concentration observation sites is limited, and the sensitivity of satellite column concentration observations to changes in near-surface concentrations is not high, resulting in significant errors in the carbon sink distribution obtained using atmospheric inverse methods. The Global Carbon Assimilation System (GCAS), developed under the support of the Ministry of Science and Technology of China and led by Nanjing University, is an atmospheric inverse and assimilation system with Chinese independent intellectual property rights. Compared to similar international products, GCAS places greater emphasis on the calculation of carbon flux as the basis of carbon assimilation using surface remote sensing data-driven ecosystem models, solving the limitations of atmospheric CO2 concentration observations. The Nanjing University team recently developed the atmospheric inverse of anthropogenic carbon emissions in the Chinese region using high-density atmospheric pollution observations, demonstrating the broad application prospects of GCAS.
