SARAL/AltiKa SCIENTIFIC OBJECTIVES
 

SARAL/AltiKa main scientific objective is the ocean meso-scale.

Ocean meso-scale variability is defined as a class of high-energy processes, with wave lengths within a 50km to 500km range, and with periods of a few days to one year. Kinetic energy of meso-scale variability is one order of magnitude more than mean circulation’s one. Description of meso-scale is thus essential for understanding ocean dynamics, including mean circulation and its climatic effects (through interactions of meso-scale turbulence with the mean flow).

SARAL/AltiKa main scientific objective is divided in sub-themes including:

    intrinsic scientific studies of ocean at meso-scale dynamics: observations, theoretical analyses, modeling, data assimilation, parameterization, ...

    improvement of our understanding of the oceanic component in the climate system: investigation of local processes at small or medium scale poorly known and understood at present, but which have an impact on the modeling of climate variability at large spatial and temporal scales.

    contribution to the study of coastal dynamic processes, especially small or medium scale phenomena, whose retrieval will enable to anticipate many downstream applications.

    contribution to operational oceanography which is seeking large amounts of in situ and space observation data.

SARAL/AltiKa secondary objectives are notably the monitoring of the main continental waters level (lakes, rivers, closed seas), the monitoring of mean sea level variations, the observation of polar oceans, the analysis and forecast of wave fields, the study of continental ices (thanks to improved performances of Ka-band) and sea ices, the access to low rains climatology (enabled in counterpart to the sensitivity of Ka-band to clouds and low rains) and the marine biogeochemistry (notably through the role of the meso and sub-meso-scale physics).
