Concentration / Utilities / Convert to ASCII not outputting vertical heights

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 ...

Re: Computed Vertical Wind Speed Values

Hi Fantine,

I've attempted this, but my file (GDAS 0.5) does not have WWND variable. Instead, HYSPLIT computes this from the horizontal velocity divergence. I was curious how I could find the values of this calculation.

Computed Vertical Wind Speed Values

Hello. When I looked in the 'Initial CONTROL File Section,' I found that if a given file does not have a vertical wind speed variable, the vertical motion will be computed from the horizontal velocity divergence. Is there any way to locate the values of the vertical motion/wind speed if given a cert...

How is exactly is the vertical motion computed from the velocity divergence

Hello. Within the 'Initial CONTROL File Section,' I understand that if a given file does not have a vertical wind speed variable, the vertical motion will be computed from the velocity divergence. Now I understand that this is a vertical integration of the horizontal velocity divergence, but what is...
