The optimal estimation method for the retrieval of atmospheric vertical profiles uses a priori information made of a profile and its covariance matrix. The underlying assumption is that the a priori profile has an averaging kernel matrix equal to the identity. The method is herewith generalized to the case that the a priori profile has a different averaging kernel matrix. The averaging kernel matrix of the a priori profile is properly taken into account in the cost function and a rigorous and more general solution for the optimal estimation method is derived.
⺠A generalization of the optimal estimation solution is provided. ⺠A priori profile is used taking into account its averaging kernel matrix. ⺠For a priori with identity averaging kernels the classical solution is obtained. ⺠Method allows rigorous exploitation of the constraint provided by observations.
