Abstract

Increased C_O2 (carbon dioxide) has been considered as one of key factors of global warming. Intending to describe the capability of CO₂ measurement by space-borne sensors quantitatively, this paper compares two data sets of CO₂ monthly products retrieved from AIRS and SCIAMACHY over China from 2003 to 2005. The increasing trend of CO₂ concentration can be detected consistently from both of the data sets. However, the seasonal variation of AIRS CO₂ is larger than SCIAMACHY CO₂ because the former represents CO₂ existing in the mid-troposphere while the latter represents in the lower-troposphere. CO₂ concentration reaches its yearly maximum in spring (April and May) and reaches its yearly minimum in late-autumn and winter (October to December and January) for both data sets. The coverage of AIRS monthly CO₂ is much better than that of SCIAMACHY over China and it shows that Xinjiang, Tibet, Inner Mongolia and northeast China have higher values than other regions in China especially in April and May due to local climate and vegetation growth process.
