Hi all,

I have been using the Concentration / Utilities / Convert to ASCII tool from the HYSPLIT GUI in an attempt to graph particle positions in an x, y, and z field. However, the columns of the output file (attached) does not appear to contain vertical heights/levels.

The column headers are 'YEAR MO DA HR LAT LON TEST05000'

Where TEST05000 appears to only output concentration levels. However, in online material I have noticed talk of levels, so I feel like they must be acheivable somehow. For instance under in the User guide it clearly states level

-x[Extended precision flag]
...
45E9.2 - Concentration data (by level and pollutant)

And in the command line in mentions this

f[File flag for a file for each pollutant-level] but this is not mentioned online. Any assitance would be greatly appreciated. Thank you

If you run with multiple levels defined in your concentration grid then the con2asc output will have multiple columns.
It looks like you currently have one particle species defined (TEST) and the 05000 indicates that is concentration from ground to 5000m.
If you defined another level (maybe 6000m) then you would have another column in your output as shown below.

YEAR MO DA HR LAT LON TEST05000 TEST06000
2012 8 29 7 45.3850 -114.2300 0.9211E-13 number

Please see here on how to define multiple levels in your concentration grid.
