This paper addresses the reconstruction of high-resolution Sea Surface Height (SSH) from the synergy between along-track altimeter data, OI-interpolated SSH fields and satellite-derived high-resolution Sea Surface Temperature (SST) fields. We aim at better resolving the fine-scale range, typically below 100km, which remains scarcely resolved by operational optimal interpolation schemes. The proposed...
This paper addresses the simulation of high-resolution geophysical fields from low-resolution satellite observations in the context of the remote sensing of the ocean surface. Within a super-resolution framework, we investigate texture-based stochastic models while controlling high-resolution spectral, geometrical and statistical features. We introduce a novel model stated as the solution of a SPDE...
Monitoring sea surface temperature (SST) is of high interest. The dynamics of climatic events such as tropical storms or cyclones are closely related to the sea surface temperature. An important research topic in oceanography is about the understanding of the interactions between the ocean's surface and it's deeper layers. In Lapeyre et al. show that in the case of baroclinic unstable flows, the potential...
This paper presents static and dynamic variational data assimilation methods for missing data interpolation in sea surface temperatures (SST) images. Evaluation using 50 AVHRR METOP SST images assesses the effectiveness of the proposed methods.
