A singular evolutive extended Kalman filter for data assimilation in oceanography

DT Pham, J Verron, MC Roubaud - Journal of Marine systems, 1998 - Elsevier
In this work, we propose a modified form of the extended Kalman filter (KF) for assimilating
oceanic data into numerical models. Its development consists essentially of approximating …

A process-convolution approach to modelling temperatures in the North Atlantic Ocean

D Higdon - Environmental and Ecological Statistics, 1998 - Springer
This paper develops a process-convolution approach for space-time modelling. With this
approach, a dependent process is constructed by convolving a simple, perhaps …
