Eulerian mean surface velocity field derived by combining drifter and satellite altimeter data

Mean Surface Circulation of the Global Ocean Inferred from Satellite Altimeter and Drifter Data

Sea level anomaly from satellite altimetry and in situ near-surface drifter velocities, combined within a simplified equation of horizontal momentum, reveal peculiar dynamical balances in the strongest known currents of the World Ocean. In the Gulf Stream, this study demonstrates the importance of centrifugal force due to the curvature of the streamlines. After filtering out Ekman currents (usi...

Reconstructing Basin-Scale Eulerian Velocity Fields From Simulated Drifter Data

A single-layer, reduced-gravity, double-gyre primitive equation model in a 2000 km 3 2000 km square domain is used to test the accuracy and sensitivity of time-dependent Eulerian velocity fields reconstructed from numerically generated drifter trajectories and climatology. The goal is to determine how much Lagrangian data is needed to capture the Eulerian velocity field within a specified accur...

Comparison of Kuroshio Surface Velocities Derived from Satellite Altimeter and Drifting Buoy Data

Sea-surface geostrophic velocities for the Kuroshio region calculated from TOPEX/ POSEIDON altimetry data together with in situ oceanographic data are compared with surface velocities derived from drifting buoy trajectories. The geostrophic velocities agree well with the observed velocities, suggesting that the Kuroshio surface layer is essentially in geostrophic balance, within measurement err...

Sea state bias in altimeter sea level estimates determined by combining wave model and satellite data

the comparison of sea surface temperature by satellite and field data of south caspian

the changes in time and location of surface temperature from a water body has an important effect on climate activities, marine biology, sea currents, salinity and other characteristics of the seas and lakes water. traditional measurement of temperature is costly and time consumer due to its dispersion and instability. in recent years the use of satellite technology and remote sensing sciences ...
