trajLevel 137An alternative way of showing the trajectories is to bin the points into latitude/longitude intervalsand average the corresponding concentrations. For these purposes trajLevel should be used. Afurther useful refinement is to smooth the resulting surface, which is possible by setting smooth = TRUE.ValueNULLNoteThis function is under active development and is likely to changeAuthor(s)David CarslawSee AlsoimportTraj to import trajectory data from the King’s College server.Examples# show a simple case with no pollutant i.e. just the trajectories# let’s check to see where the trajectories were coming from when# Heathrow Airport was closed due to the Icelandic volcanic eruption# 15--21 April 2010.# import trajectories for London and plot## Not run:lond
