Regularization of the ensemble Kalman filter using a non-parametric, non-stationary spatial model
Michael Tsyrulnikov, Arseniy Sotskiy
The sample covariance matrix of a random vector is a good estimate of the true covariance matrix if the sample size is much larger than the length of the vector. In high-dimensiona…
Impact of non-stationarity on hybrid ensemble filters: A study with a doubly stochastic advection-diffusion-decay model
Michael Tsyrulnikov, Alexander Rakitko
Effects of non-stationarity on the performance of hybrid ensemble filters are studied (by hybrid filters we mean those which blend ensemble covariances with some other regularizing…
A Hierarchical Bayes Ensemble Kalman Filter
Michael Tsyrulnikov, Alexander Rakitko
A new ensemble filter that allows for the uncertainty in the prior distribution is proposed and tested. The filter relies on the conditional Gaussian distribution of the state give…
