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...

A Rotating Knife-beam Altimeter for Wide-swath Remote Sensing of Ocean: Wind and Waves

The use of a nadir altimeter radar with a rotating knife-beam antenna pattern is considered for improved measurements of the sea surface wind and wave parameters over a wide swath. Theoretical calculations suggest the antenna beam rotating about the vertical axis is able to provide wide swath of order 250-350 km. Processing of the signals using time or Doppler sampling techniques results in the...

A comparison of ocean topography derived from the Shuttle Laser Altimeter-01 and TOPEX/POSEIDON

To assess the utility of laser altimetry for studies in dynamical oceanography, we present a comparison of the Shuttle Laser Altimeter (SLA)-01 and the TOPEX/POSEIDON (T/P) radar altimeter on global and regional scales. We compare all 1.1 million SLA-01 range measurements over the oceans to the CSRMSS95 gridded mean sea surface model and find the overall root mean square (RMS) difference to be ...

The Research on Ocean Surface Wind Speed Retrieval by Neural Network Algorithm for HY2 Altimeter

The neural network algorithm in this paper is applied to the ocean surface wind speed retrievals. Firstly, the Ku band backscattering coefficient (σKu) is considered as the input parameter to retrieve the wind speed and the retrieval precision reaches 1 m/s (root mean square error) for HY2 altimeter. Secondly, by introducing the Ku-band significant wave height (swhku), C-band backscattering coe...
