Apply HYSPLIT to very small area (100x100 m^2)

Post by AndyLu » March 15th, 2019, 8:52 am

Dear HYSPLIT Community,

The atmospheric dispersion modeling I'd like to carry out is related to a quite small area of about 100x100 m^2, in particular a small open-air waste water treatment plant which emits small but sometimes notable concentrations of hydrogen sulfide.

Since the online test runs I've conducted so far seem to apply solely on much larger areas, I wonder if
it is also possible to display atmospheric dispersion on a comparably very small scale, say on an area around the odorant/gas source of about 100 to 200 m diameter?

Thank you very much for your advice,

You can specify a very high resolution concentration grid in HYSPLIT.

However please see this discussion:
Limitations include a minimum 1 minute time step and the resolution of the meteorological data.
