• Description:
  Iterativeensemblefiltersandsmoothersarenowcommonlyusedforgeophys- ical models. Some of these methods rely on a factorization of the observation likelihood function to sample from a posterior density through a set of “tem- pered”transitionstoensemblemembers.ForGaussian-baseddataassimilationmethods, tangent linear versions of nonlinear operators can be relinearized betweeniterations,thusleadingtoasolutionthatislessbiasedthanasingle-step approach.Thisstudyadoptssimilariterativestrategiesforalocalizedparticlefil-ter(PF)thatreliesontheestimationofmomentstoadjustunobservedvariables
