and for point sources. FLEXPART distinguishes between the two using the lower altitude of the release box: area sources are
assumed to start below 0.5 m above the ground, whereas point sources are assumed to be higher. Please note that when this
option is used, it is not so easy to determine the maximum number of particles present at a particular time of the model run. It
might then be necessary to increase the parameter maxpart to a higher value than what would otherwise be needed.
