| Zusammenfassung |
| Sea ice thickness information is important for sea ice modelling and
ship operations. Here a method to detect the thickness of sea ice
up to 50 cm during the freeze-up season based on high incidence angle
observations of the Soil Moisture and Ocean Salinity (SMOS) satellite working at 1.4 GHz is
suggested. By comparison of thermodynamic ice growth data with
SMOS brightness temperatures, a high correlation to intensity
and an anticorrelation to the difference between vertically and
horizontally polarised brightness temperatures at incidence angles
between 40 and 50° are found and used to develop an empirical
retrieval algorithm sensitive to thin sea ice up to 50 cm thickness.
The algorithm shows
high correlation with ice thickness data from airborne measurements
and reasonable ice thickness patterns for the Arctic freeze-up
period. |
