flexpartplot_latlon.f              plots normal FLEXPART forward simulation results
flexpartplot_backward_latlon.f     plots FLEXPART backward simulation results for a certain receptor: ATTENTION REVERSES RECEPTOR NUMBERING
flexpartplot_backward_latlon_sum.f plots FLEXPART backward simulation results for a certain receptor, accumulated over all time steps (i.e., ages): ATTENTION REVERSES RECEPTOR NUMBERING
flightleg_flexpartplot_latlon.f    same as flexpartplot_latlon.f, but reads in aircraft position data and overlays the flight track over the FLEXPART results
