Meteorology error

[gkrkpm]

hi
I am facing problems while executing the model. Is that I need to add meteorology data for simulation?
Simulation Log showing the following error:

Model started ...

Yes, you need to click on the "Add Meteorology Files" button to add a HYSPLIT formatted meteorological data set. Meteorology files can be downloaded to the PC through the Meteorology pull down menu.
