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.
