| Zusammenfassung |
| We present a sea-level reconstruction for the Arctic Ocean using recent satellite altimetry
data. The model, forced by historical tide gauge data, is based on empirical orthogonal
functions (EOFs) from a calibration period; for this purpose, newly retracked satellite
altimetry from ERS-1 and -2 and Envisat has been used. Despite the limited coverage of
these datasets, we have made a reconstruction up to 82 degrees north for the period
1950–2010.
We place particular emphasis on determining appropriate preprocessing for the tide gauge
data, and on validation of the model, including the ability to reconstruct known data. The
relationship between the reconstruction and climatic variables, such as atmospheric
pressure, and climate oscillations, including the Arctic Oscillation (AO), is examined. |
