A Brief Tutorial on Data Assimilation with Hydrologic Applications

Data assimilation is a method in which observations are used as initial conditions to update numerical simulations with an optimal interpolation. Such nudging techniques have been traditionally used in numerical weather prediction, where the forecast state and initial state are minimized. Here we will provide a historical overview, a discussion of the basics of data assimilation, and an application of assimilation techniques to climate and land surface hydrology.
