Re: Depositions calculated with the puff mode of HYSPLIT

Please check your MESSAGE file to see if you run out of puff after splitting. If that occurred you should get a Warning message in the MESSAGE file.

Re: HYSPLIT on Mac OS Mojave

To make HYSPLIT run in Mojave you will have to go to System Preferences and then to Security & Privacy. Under the Privacy tab look for Accessibility. You should check the HYSPLIT4 icon in the window. Also, once the HYSPLIT Graphical User Interface launches you will not be able to see the buttons (we...

Re: Resolution of reanalysis data

For GDAS ARL produces a 3 hourly, global, 1 degree latitude longitude dataset on pressure surfaces. For the reanalysis we produce a 2.5 degree latitude-longitude global grid with output every 6 hours. For more information about the available meteorological datasets that you can use with HYSPLIT, ple...

Re: NUMPAR v emission rate

The number of particles released per cycle NUMPAR (2500) would be the maximum number of particles or puffs released over the duration of the emission. NUMPAR has a different meaning for puff and particle simulations. In a full puff simulation (INITD = 1 or 2), only one puff per time step is released...

Re: EMITIMES

If you are using the GUI, go to Advanced / File Edit / Emissions File This menu creates the optional EMITIMES file which is used to configure more complex point source emissions scenarios. In the standard model simulation, the CONTROL file can only be used to define one pollutant release cycle which...
