Re: Uncertainty along trajectory endpoint

Dear Ariel, Thanks for your answer. It is rather comforting that this makes sense. Few more questions though: should this noise be function of time AND wind speed standard deviation, or could it be only function of ws stdev ? Because, in the case of receptor modelling, the further back in time we're...

Uncertainty along trajectory endpoint

Hi all, For the purpose of a particular study (trajectory analysis by eg PSCF), I was wondering if I could implement uncertainty to the backtrajectory's endpoints coordinates. I figured that this uncertainty should increase with time so that it could account a little bit for dispersion. So, for each...

Re: SETUP.CFG causing calculation abortion

Damn it was that simple... Just updated the model and it works nicely. Sorry for that, and thank you very much for your help!

Re: SETUP.CFG causing calculation abortion

Yes, I just tried with your SETUP file, but it unfortunately resulted in an aborted run... :(
I just sent the screenshot.

Thanks!

Re: SETUP.CFG causing calculation abortion

Surprising... The SETUP.CFG is automatically generated from an Igor code (enclosed image, and there is no hidden characters... I managed to get a screenshot of the command window when the calculation aborts (second enclosed image): Looks like hyts_std doesn't recognize tm_sphu as a namelist variable...

Re: SETUP.CFG causing calculation abortion

I am using weekly GDAS files, directly downloaded from your ftp. The weird thing is that even if tm_sphu or tm_mixr equals 0, calculation is aborted... Looks like hyts_std doesn't recognize these variables anymore. It has worked perfectly before, and same thing also occurred to other users of my bat...

Re: SETUP.CFG causing calculation abortion

Thanks for the tip. I just tried and it did not work.
Then I removed tm_sphu and tm_mixr because I didn't see them in the namelist variables in the user guide, and it surprisingly worked ! Is it normal? Are these variables not supported anymore?

Re: SETUP.CFG causing calculation abortion

Thanks for the tip. I just tried, and it did not work...
But then, I removed tm_sphu and tm_mixr (because these 2 variables are not listed in the namelist variables), and it worked ! Is it normal?
Are these variables not available anymore?

SETUP.CFG causing calculation abortion

Dear all, I launch HYSPLIT from a batch file, creating the CONTROL file, and I am also generating a SETUP.CFG file to add meteorological variables in the trajectory file. For an unknown reason the SETUP.CFG is causing the calculation not to perform (whereas, when the file is not generated, calculati...

Re: Analyzing trajectory frequency output files in IGOR

Dear Bryan, It might be way too late, so you probably found your way to import backtrajectories into Igor... But just to let you know that since several months, an Igor procedure has been available to handle backtrajectories. Please visit https://sites.google.com/site/zefirproject/home to see if thi...
