Satellites provide a surface signature of the temperature of the ocean with a high horizontal resolution while in situ autonomous probes supply high vertical resolution , but horizontally sparse, knowledge of the ocean interior thermal structure. The objective of this paper is to develop a methodology to combine these complementary ocean observing systems measurements to obtain a three-dimensional time series of ocean temperatures with high horizontal and vertical resolution. Within an observation-driven framework, we investigate the extent to which mesoscale ocean dynamics in the North Atlantic region may be decomposed into a mixture of dynamical modes, characterized by different local regressions between Sea Surface Temperature (SST), Sea Level Anomalies (SLA) and Vertical Temperature fields. Ultimately we propose a Latent-class regression method to improve prediction of vertical ocean temperature. %G English %2 https://imt-atlantique.hal.science/hal-02928416/document %2 https://imt-atlantique.hal.science/hal-02928416/file/1910.08573.pdf %L hal-02928416 %U https://imt-atlantique.hal.science/hal-02928416 %~ IRD %~ INSU %~ UNIV-BREST %~ INSTITUT-TELECOM %~ CNRS %~ UNIV-UBS %~ IFREMER %~ IUEM %~ THESES_IUEM %~ GIP-BE %~ ENIB %~ LAB-STICC %~ LOPS %~ LAB-STICC_IMTA_CID_TOMS %~ IMTA_SC %~ LAB-STICC_IMTA %~ IMT-ATLANTIQUE %~ PRACOM %~ INSTITUTS-TELECOM %~ IMTA_MEE
