2014/4/30
This investigation employs the use of ICESat to derive freeboard measurements in McMurdo Sound in the western Ross Sea, Antarctica, for the time period 2003-2009. Methods closely follow those previous...
Ensemble Kalman filter assimilation of temperature and altimeter data with bias correction and application to seasonal prediction
Kalman filter assimilation temperature and altimeter data bias correction and application seasonal prediction
2009/11/9
To compensate for a poorly known geoid, satellite altimeter data is usually analyzed in terms of anomalies from the time mean record. When such anomalies are assimilated into an ocean model, the bias ...
Wave data collection using satellite altimeter data in Indonesian domestic sea
