英文摘要	Methane is an important anthropogenic greenhouse gas and is increasing steadily since the industrial revolution. SCIAMACHY on ENVISAT is the first satellite instrument whose measurements are sensitive to concentration changes of methane gas at all altitude levels down to the Earth's surface where the source/sink signals are largest. To retrieve the methane column amount from SCIAMACHY data, the methane absorption cross section is the prerequisite reference parameter. We based on theoretical calculation and calculate the methane cross section with HITRAN2004 and HITRAN2008 respectively. The results showed that there exits huge difference between the two cross sections. In order to improve the retrieval accuracy of methane column amount, we come to conclude that HITRAN2008 is the better choice for future calculation research.
