| Zusammenfassung |
| Extensive ozone measurements were made during the second SAGE III Ozone Loss and
Validation Experiment (SOLVE II). We compare high-latitude line-of-sight (LOS)
slant column ozone measurements from the NASA DC-8 to ozone simulated by forward
integration of measurement-derived ozone fields constructed both with and
without the assumption of horizontal homogeneity. The average bias and rms
error of the simulations assuming homogeneity are relatively small (−6 and
10%, respectively) in comparison to the LOS measurements. The comparison
improves significantly (−2% bias; 8% rms error) using forward integrations
of three-dimensional proxy ozone fields reconstructed from potential
vorticity-O3 correlations. The comparisons provide additional verification
of the proxy fields and quantify the influence of large-scale ozone
inhomogeneity. The spatial inhomogeneity of the atmosphere is a source of error
in the retrieval of trace gas vertical profiles and column abundance from LOS
measurements, as well as a complicating factor in intercomparisons that include
LOS measurements at large solar zenith angles. |
