| Zusammenfassung |
| The Ozone Mapper and Profiler Suite, Limp Profiler (OMPS/LP) algorithm is
used to retrieve ozone concentration and aerosol extinction profiles using a
series of 120 SCIAMACHY limb measurements collocated with SAGE II solar
occultation events. The primary goal of the study is to ascertain the
capability of the OMPS/LP retrieval algorithm to accurately retrieve the
vertical distribution of stratospheric aerosol extinction coefficient so as
to better account for aerosol effects in the ozone profiling retrieval
process. Using simulated radiances, we show that the aerosol extinction
coefficient can be retrieved from limb scatter measurements within 5% and
a standard deviation better than 15%, which is more than sufficient to
improve the OMPS/LP ozone products to be used as Environmental Data Records.
We also illustrate the ability of SCIAMACHY limb measurements to retrieve
stratospheric aerosol extinction profiles with accuracy comparable to other
instruments. The retrieved aerosol extinction profiles agree with collocated
SAGE II measurements on average to within 25%, with a standard deviation
of 35%. |
