| 英文摘要 | In this study, the Chinese carbon cyle data-assimilation system Tan-Tracker is developed based on the atmospheric chemical transport model (GEOS-Chem) platform. Tan-Tracker is a dual-pass data-assimilation system in which both CO2 concentrations and CO2 fluxes are simultaneously assimilated from atmospheric observations. It has several advantages, including its advanced data-assimilation method, its highly efficient computing performance, and its simultaneous assimilation of CO2 concentrations and CO2 fluxes. Preliminary observing system simulation experiments demonstrate its robust performance with high assimilation precision, making full use of observations. The Tan-Tracker system can only assimilate in situ observations for the moment. In the future, we hope to extend Tan-Tracker with functions for using satellite measurements, which will form the quasi-operational Chinese carbon cycle data-assimilation system. |
