The retrieved aerosol profiles are compared with Stratospheric Aerosol and Gas Experiment（SAGE） Ⅱ aerosol data records. The comparisons are made over the period 2003–2004. The results show that the SCIAMACHY aerosol profile retrievals exhibit general agreement with the coincident SAGE Ⅱ data records. In the 15–35 km altitude range, the percentage differences between the SCIAMACHY-retrieved and SAGE Ⅱ–measured zonal mean aerosol extinction profiles are less than 20% for the 20–30°N and 30–40°N latitude zones, and less than 25% for the 40–50°N zone. The stratospheric aerosol optical depths in this altitude range calculated from SCIAMACHY retrievals are in good agreement with SAGE Ⅱ measurements, with present differences less than 6% for the three latitude zones. The aerosol retrievals from SCIAMACHY observations are combined with the SAGE Ⅱ aerosol data records, form a long-term data-set for the period 2000–2010. Using the combined SAGE Ⅱ and SCIAMACHY dataset, the variation trends of the stratospheric aerosol layer over East Asia（20–50°N, 70–150°E） are analyzed. The results indicate that the stratospheric aerosols have a significant trend of increase over East Asia during 2000–2010. The stratospheric aerosol optical depths increase by about 5% per year over the 11-yr period. The increase in stratospheric aerosols is found to be obviously related to moderate volcanic eruptions.展开更多
