ABSTRACT
Within the SHOM/BRESM assimilation group in Toulouse, France, we are investigating means of assimilating ARGO float displacement data into a regional open-boundary implementation of MICOM. The model area covers a small part of the North Atlantic Ocean off the portugese coast, where intensive surveys and float releases were performed in years 2000 and 2001 within the french POMME experiment.
Our special topic of interest is the behaviour of assimilation methods with respect to mesoscale structures such as eddies and fronts. The ARGO float cycle of typically 10 days introduces weak or strong aliasing of the structures.
The methods beeing developed and tested include various implementation of objective analysis as well as variational methods. Our approach is pragmatic : the methods are implemented and their performances for analysis and forecast are compared. We will expose our model and assimilation setup and show some preliminary results.
