Kalman filter – Wikipedia – Kalman filtering, also known as linear quadratic estimation (LQE), is an algorithm that uses a series of measurements observed over time, containing statistical noise.

We compare the observation impact calculated from the proposed ensem- ble sensitivity method with that from the adjoint method, and further compare the observation impacts calculated from both methods with the actual forecast error reduc- tion due to assimilation of these observations in the. Lorenz 40-variable model.
