Do the vertical distribution of the particles, in example 7.1, is system configuration (hardware) dependent? I am asking, since the vertical profiles in MESSAGE file showed by Roland Draxler obtained values different by more than 10% from mine.

Theoretically, all dispersion simulations are different because they involve random number generation by machine. Not sure 10% deviation is common, but the results surely can differ depending on machines (and met data, modeling configurations etc.).

I meant of the order of 10%.

Thank you for the reply.
