摘要

Stratospheric ozone mixing ratio profiles measured by satellite-borne Stratospheric Aerosol and Gas Experiment (SAGE II data version 5.93) and Halogen Occultation Experiment (HALOE data versions 17 and 18) are compared with each other and with balloon-borne ozonesonde profiles at Payerne, Lauder, and Macquarie Island stations during 1994-1995. The SAGE II-HALOE ozone mixing ratio profiles are compared at 13-55 km altitudes, and the satellite-ozonesonde profiles are compared at 13-33 km altitudes. It is found that HALOE data version 18 ozone values are systematically larger than HALOE data version 17, particularly in the lower stratosphere. HALOE data version 18 ozone profiles are about 2%, 5-8%, and 10-20% larger than the corresponding HALOE data version 17 at 40-55, 25-40, and 15-25 km altitudes, respectively. The new version of HALOE ozone agrees better with SAGE II and Payerne ozonesonde profiles than HALOE data version 17 does. In general, the agreements between satellite-borne sensors and ozonesondes are all within their stated level of uncertainties, Intercomparison results between SAGE II-Payerne ozonesonde and SAGE II-Lauder ozonesonde are compared with earlier comparative studies between SAGE I-Payerne ozonesonde and SAGE II-Lauder ozonesonde by Veiga et al. [1995], Better agreement is achieved at Payerne station, but no improvement is discernible at Lauder ozonesonde station. At altitudes above 20 km the intercomparisons between SAGE II and HALOE data version 18 and between SAGE II and ozonesondes seem to indicate that aerosol has no statistically significant impact on SAGE II ozone retrieval during the period of 1994-1995.
