This work is devoted to the problem of obtaining an estimate of methane emissions using satellite data and the results of mathematical modeling. To implement the algorithm, a variant of the local Kalman ensemble filter (LETKF) is used, which represen

In the ensemble Kalman filter, a currently popular data assimilation algorithm, it is assumed that the density of the estimation error distribution is a Gauss function, which is not fulfilled in the general case of a nonlinear model and a nonlinear o

A practical realization of the data assimilation algorithm based on the Kalman filter in its non-simplified form is impossible for modern forecast models because of the high dimension of the associated sets of equations and nonlinearity of predicted
