摘要： 利用中国南极科学考察第24航次采集的大气CO2浓度与AIRS的大气红外辐亮度进行统计回归，获取两者间的拟合关系。与该航次随机选取的60°S附近验证点比较，平均相对偏差为1.09%。同时，将拟合函数应用于对应第26航次同位置、近时间点的AIRS大气辐射值，其结果和第26航次走航数据进行比对，平均相对偏差为2.12%。对比同纬度下第24航次的精度，其精度有明显的下降，结果表明，利用统计回归的计算方式具有一定的局限性。

Abstract: An algorithm was built by statistical regression using the data of atmospheric CO2 along the tract during the 24th CHINARE (Chinese National Arctic and Antarctic Administation) and the AIRS’s radiance. The verification points around latitude 60°south were picked up and the average error was 1.09%, which precise is higher than GOSAT that is special satellite to observe the atmospheric CO2. The AIRS’s radiance, which position and time are near to the 26th cruises’, was put into the algorithm. The average error was 2.12%. It is shown that the algorithm basing on regression statistic has some limitation.
