1 Combining Argo and remote-sensing data in the North Atlantic
Despite the impressive increase of the number of temperature and salinity profiles from the Argo array, in-situ data still undersample the temporal and spatial variability of the ocean thermohaline structure. In contrast, remote-sensing measurements provide synoptic observations of sea level and sea...

| Summary: | Despite the impressive increase of the number of temperature and salinity profiles from the Argo array, in-situ data still undersample the temporal and spatial variability of the ocean thermohaline structure. In contrast, remote-sensing measurements provide synoptic observations of sea level and sea surface temperature (SST) over the world ocean, but with no direct estimation of the ocean’s vertical structure. In order to reconstruct instantaneous temperature (T) fields at high temporal and spatial resolution, a merging method is developed to combine the accurate but sparse in-situ T profiles with the high-resolution but less accurate (as synthetic T profiles) altimeter and SST measurements. |
