| Zusammenfassung |
| In order to evaluate the variability of the sea surface temperature (SST) in the Western
Mediterranean Sea between 1985 and 2005, an integrated approach combining geostatistical
tools and modelling techniques has been set up. The objectives are:
underline the capability of each tool to capture characteristic phenomena,
compare and assess the quality of their outputs,
infer an interannual trend from the results.
Diva (Data Interpolating Variationnal Analysis, Brasseur et al. (1996) Deep-Sea Res.)
was applied on a collection of in situ data gathered from various sources (World Ocean
Database 2005, Hydrobase2, Coriolis and MedAtlas2), from which duplicates and suspect
values were removed. This provided monthly gridded fields in the region of interest.
Heterogeneous time data coverage was taken into account by computing and removing the
annual trend, provided by Diva detrending tool. Heterogeneous correlation length was
applied through an advection constraint.
