| Zusammenfassung |
| Direct observation of the Sun at large solar zenith angles during the second
SAGE III Ozone Loss and Validation Experiment (SOLVE II)/Validation of
International Satellites and study of Ozone Loss (VINTERSOL) campaign by several
instruments provided a rich dataset for the retrieval and analysis of
line-of-sight column composition, intercomparison, and measurement validation.
A flexible, multi-species spectral fitting technique is presented and applied to
spectral solar irradiance measurements made by the NCAR Direct beam Irradiance
Atmospheric Spectrometer (DIAS) on-board the NASA DC-8. The approach allows for
the independent retrieval of O3, O2·O2, and aerosol optical properties, by
constraining Rayleigh extinction. We examine the 19 January 2003 and 6 February 2003
flights and find very good agreement of O3 and O2·O2 retrievals with
forward-modeling calculations, even at large solar zenith angles, where
refraction is important. Intercomparisons of retrieved ozone and aerosol
optical thickness with results from the Ames Airborne Tracking Sunphotometer
(AATS-14) are summarized. |
