Chapter 6 - Ensemble-based atmospheric data … Web6.2 Bayesian data assimilation Conceptually, the atmospheric data assimilation problem is a relatively simple one. The task at hand is to estimate accurately the probability density function (pdf) for the current atmospheric state given all current and past observations. Much of the material in this section follows Anderson and Anderson (1999).
