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 ...
Toward the Application of the Kalman Filter to Regional Open Ocean Modeling
Kalman Filter Regional Open Ocean Modeling
2009/1/10
As ocean models improve, assimilation of data with the help of models becomes increasingly important. The Kalman filter provides a method for assimilation of data that are arbitrarily distributed in t...
Ocean Data Assimilation and the Moan Filter：Spatial Regularity
Ocean Data Assimilation Moan Filter Regularity
2009/1/8
Ocean circulation models are infinite-dimensional dynamical systems. If the Kalman filter is used to assimilate data into such systems, then their infinite-dimensionality must be recognized. In other ...
A Kalman Filter Analysis of Sea Level Height in the Tropical Pacific
Kalman Filter Analysis Sea Level Height Tropical Pacific
2008/12/30
The Kalman filter is implemented and tested for a simple model of sea level anomalies in the tropical Pacific, using tide gauge data from six selected island stations to update the model. The Kalman f...
Estimation of Tropical Sea Level Anomaly by an Improved Kalman Filter
Tropical Sea Level Kalman Filter long-wave model
2008/12/10
Kaiman filter theory and autoregressive time series are used to map sea level height anomalies in the tropical Pacific. Our Kalman filters are implemented with a linear state space model consisting of...
Comparison of robust H∞ filter and Kalman filter for initial alignment of inertial navigation system
H∞ filter Kalman filter initial alignment integrated navigation system SINS
2011/9/14
There are many filtering methods that can be used for the initial alignment of an integrated inertial navigation system.This paper discussed the use of GPS,but focused on two kinds of filters for the ...
Change in filter-screen morphology and depth selection: Uncoupled responses of Daphnia to the presence of filamentous cyanobacteria
filter-screen morphology depth selection: Uncoupled responses filamentous cyanobacteria
2014/4/21
In many eutrophic lakes, ability to cope with filamentous cyanobacteria is crucial to Daphnia fitness, as the filaments can reduce food intake by interference with food-particle retention. Two basic m...
A bio-oceanographic filter to larval dispersal in a reef-building coral
A bio-oceanographic filter larval dispersal reef-building coral
2014/5/5
Gene flow was shown to be limited between western and eastern Caribbean populations of the reef-building coral, Acropora palmata. However, some mixing was detected among populations near Puerto Rico. ...
Minireview: Ciliary filter feeding and bio-fluid mechanics—present understanding and unsolved problems
Minireview Ciliary filter feeding biofluid mechanics present understanding unsolved problems
2014/6/9
The energy cost for various ciliary filter feeders shows that useful pump work constitutes 0.3-1.1% of the total metabolic expenditure. The ‘water processing potential’ (liters of water pump...
