This processor writes out the shape and the pathogen load of all AerosolClouds. Each row corresponds to one aerosol cloud at a given simulation time. The shape of an aerosol cloud is described by the radius and its center ([x, y]-coordinates).
To reduce the size of the output file, one can reduce the sample frequency, that is the processor writes out only every {@param sampleEveryNthSimStep}.
