Data Assimilation is a mathematical and computational framework within the broader class of state estimation methods that systematically integrates observational data with numerical models to improve the accuracy of the modeled system state by minimizing uncertainties arising from model errors and incomplete initial conditions, particularly in dynamic geophysical systems such as the atmosphere and hydrosphere.
