Simulations of ARGO profilers and of surface floating objects: applications in MFSTEP

[摘要] In this work we describe part of the activities performed in the MFSTEP project by meansof numerical simulations of ARGO profilers and surface floating objects.Simulations of ARGO floats were used to define the optimal time cycling in orderto maximize independent observations of vertical profiles of temperature andsalinity and to minimize the error on the estimate of the velocity at the parking depth of the profilers.Instead, the Mediterranean Forecasting System archive of Eulerian velocity field from 2000to 2004 was used to build a related surface Lagrangian archive, systematically integrating numericalparticles released and constrained to drift at surface. Here we use such Lagrangian archive to study theinterannual variability of the surface Lagrangian transport in two key areas of the Western Mediterranean,also introducing an exponential decay in the particles concentration.
