Session: Science II: From large-scale oceanography to coastal and shelf processes

Presentation type: Type Poster

Over the last decade, great progress has been made in both coastal altimetry and high resolution ocean modeling. Their use (together or separately) is rapidly evolving. One fundamental issue is then to understand the capabilities of the different coastal altimetry data products and of the different models for coastal applications.

In this work, the purpose is the definition of diagnoses which can be computed from coastal alongtrack sea level anomaly products and are adapted to the monitoring of the coastal ocean dynamics.

In the framework of the Copernicus program, a new software is under development at the Laboratoire d'Etude en Géophysique et Océanographie Spatiales (France), in collaboration with CLS. The two complementary objectives are:

- the development of new altimetry data validation/intercomparison methods, adapted to the finer scales of the coastal dynamics.
- the analysis of the performance of different high resolution numerical models thanks to alongtrack altimetry measurements.

This tool is based on the inter-comparison between coastal altimetry data sets, model outputs and in-situ measurements. Among these comparisons it is possible to focus on sea level, absolute surface currents or geostrophic surface currents. Different and complementary diagnoses are available. Their combined analysis provides information on the temporal and spatial variability of the coastal ocean dynamics which are captured by altimetry and models, respectively.

In this work, the project will be introduced, some example of diagnoses will be presented and results will be discussed.
