Re: HYSPLIT error

Are you using the multi-processor hycm_std? or hycs_std? I am using hycm_std with 4 threads. Can you please attach a MESSAGE file. The MESSAGE file may be PDF. I am in the process of getting this uploaded. When is the program failing? Does it fail right when you start HYSPLIT or at a particular tim...

Re: HYSPLIT error

Good Morning, I have increased MAXPAR, varied KHMAX and decreased the grid size but I am still getting the same error: It seems that the EMITIMES file can only have 10 days worth of releases unless I set KHAMX to be very small at which point the plume has barley left the release point. Ideally I wan...

Re: HYSPLIT error

I've attached the input files. I might have to attach the pdf of the MESSAGE file as I am running this on a separate system.

Re: HYSPLIT error

The emission rates are averaged over 24 hours so I think I have to keep emission duration as 24 hours.

Re: HYSPLIT error

I was able to reduce the number of entries in the EMITIMES file and the simulation was able to complete. The simulation will complete if I stop releasing on the 21st (so a total of 22 entries) . Is there a variable that I need to change so I can use more sources in the EMITIMES?

HYSPLIT error

I am getting the following error:

forrtl:error(69): process interrupted (SIGINIT)

after the simulation starts. I have attached the error, SETUP, CONTROL and EMITIMES file.

Thanks

NUMPAR Clarification

The manual states that " NUMPAR represents the total number of particles that are released during one release cycle " and a similar thread states that " The actual particle release rate is computed by dividing NUMPAR by the number of sources and release hours ". So when you are releasing n number of...

Re: Wind Profile

The global reanalysis data also gives the variables as a function of geopotential height. Is it possible to convert this into height above ground levels or is it better to use the hypsemtric equation https://en.wikipedia.org/wiki/Hypsometric_equation to calculate the height from the pressure levels?
