摘要：

In this paper two data assimilation methods for the two-dimensional advection-diffusion equation are developed for the estimation and prediction of air pollution. First, a time-invariant Kalman filter is developed by using Chandrasekhar-type filter algorithm. Then, as an alternative, a simpler data assimilation method based on Kriging is also proposed. The two data assimilation methods are compared in a number of experiments. (C) 1997 by Elsevier Science Inc.
