| Zusammenfassung |
| The OSIRIS instrument onboard the Odin spacecraft routinely measures
vertical profiles of spectrally dispersed, limb scattered sunlight
from the upper troposphere into the lower mesosphere. These
measurements are used to retrieve the ozone number density vertical
profile using the SaskMART Multiplicative Algebraic Reconstruction
Technique, which is a one dimensional modification of an existing
two-dimensional tomographic retrieval algorithm. The retrieved
profile extends from the cloud top to 60 km. In the absence of
clouds the retrieval extends down to 10 km. This technique allows
for the consistent merging of the absorption information from
radiance measurements at wavelengths in the Chappuis and the
Hartley-Huggins bands at each iteration of the inversion. The
effectiveness of the retrieval is demonstrated using a set of
coincident SAGE II occultation measurements that show a mean bias of
less than 2% from 18 to 53 km. |
