| Zusammenfassung |
| The study of sea ice using airborne remote sensing platforms provides
unique capabilities to measure a wide variety of sea ice properties.
These measurements are useful for a variety of topics including model
evaluation and improvement, assessment of satellite retrievals, and
incorporation into climate data records for analysis of interannual
variability and long-term trends in sea ice properties. In this paper
we describe methods for the retrieval of sea ice thickness, freeboard,
and snow depth using data from a multi-sensor suite of instruments
on NASA's Operation IceBridge airborne campaign. We assess the consistency
of the results through comparison with independent data sets that
demonstrate that the IceBridge products are capable of providing a
reliable record of snow depth and sea ice thickness. We explore the
impact of inter-campaign instrument changes and associated algorithm
adaptations as well as the applicability of the adapted algorithms
to the ongoing IceBridge mission. The uncertainties associated with
the retrieval methods are determined and placed in the context of
their impact on the retrieved sea ice thickness. Lastly, we present
results for the 2009 and 2010 IceBridge campaigns, which are currently
available in product form via the National Snow and Ice Data Center. |
