Influence analysis of Arctic tide gauges using leverages | Peter Limkilde Svendsen, Ole Baltazar Andersen, Allan Aasbjerg Nielsen
| | Abstract | Reconstructions of historical sea level in the Arctic Ocean are fraught with difficulties related to lack of data, uneven distribution of tide gauges and seasonal ice cover. Considering the period from 1950 to the present, we attempt to identify conspicuous tide gauges in an automated way, using the statistical leverage of each individual gauge. This may be of help in determining appropriate procedures for data preprocessing. We use a model based on empirical orthogonal functions from a calibration period, in this preliminary case Drakkar ocean model data, which are forced using historical tide gauge data from the PSMSL database. | | Type | Conference paper [With referee] | | Conference | EGU General Assembly | | Year | 2014 Month April | | BibTeX data | [bibtex] | | IMM Group(s) | Computer Science & Engineering, Geoinformatics |
