Abstract - A temporal interpolation technique has been developed that uses meteorological information to show the evolution of an average air concentration pattern into its next time period average.  Forward and backward trajectories are constructed from every point at the desired time to the next and previous time period patterns.  The concentration is then the weighted average of the concentrations at the respective trajectory endpoints. The technique can be used to smooth transitions between successive images for movie animations or video presentations.  An example sequence from the ANATEX video is shown.
