This work extends the estimator developed in Part 1 of this study to the problem of estimating a turbulent channel flow at $Re_{\tau}\,{=}\,100$ based on a history of noisy measurements on the wall. The key advancement enabling this work is the development and implementation of an efficient techniqu...
