文摘
- •
We present an efficient algorithm that blends drifter data and altimetry data.
- •
It is used to continuously improve surface velocity estimation in the East-Med.
- •
Assimilating a drifter datum gives correction in a radius of 20 km and a 24 h window.
- •
Improvement of velocity estimation is shown near the Lebanese coast.
- •
Accurate eddy estimation (dimension and intensity) in S.E. of Cyprus is shown.
