摘要
Abstract
Tan-Tracker碳卫星资料联合数据同化系统是针对即将发射的中国的碳卫星TANSat,并基于先进数据同化算法PODEn4DVar,同时采用了联合数据同化的策略,紧扣碳卫星资料同化的这一国际前沿开发的面向科研和应用的碳卫星资料同化系统.本文设计运行了Tan-Tracker碳卫星资料联合数据同化系统同化GOSAT卫星CO2 浓度观测的真实同化实验,并评估了Tan-Tracker碳同化系统的可行性和有效性.经过同化后的结果与模式模拟结果同观测对比,均方根误差有了明显的下降(约30%),特别是在地面观测严重缺失的非洲北部、印度半岛、南部非洲、美国南部、澳大利亚西部等地;同时与观测的相关系数并无很大的差异.总体而言,Tan-Tracker碳同化系统成功完成真实数据同化并有较好的结果.关键词
