Description:The characteristics of several damping time integration methods, which have been used in four-dimensional data assimilation, are examined theoretically and experimentally. Included are two explicit methods, two semi-implicit methods, and a viscous method. The results indicate that, although there are differences in capability to damp gravitational noise, all the methods performed equally well in an experimental assimilation of real data.
