DOI: 10.1002/qj.3852
Abstract: The Local Ensemble Transform Kalman Filter (LETKF) computes analysis by using a weighted average of the first‐guess ensemble with surrounding observations within a localization cut‐off radius. Since overlapped observations are assimilated at neighbouring grid points,… read more here.

Abstract: One of the vital processes that should be monitored and analyzed continuously in the oil-gas and petroleum-related industries is the multi-phase flow inside pipes. Multi-phase flow means flowing two or more phases of gas, liquid,… read more here.

Abstract: AbstractMany ensemble data assimilation (DA) approaches suffer from the so-called “inbreeding” problem. As a consequence, there is an excessive reduction in ensemble spread by the DA procedure, cau... read more here.
