Re: Fatal Error 900

What meteorological data did you use? Check if you have files for May and June because you are computing backward trajectory starting at June 1st 00 UTC.
You should also set the model top to a higher altitude, like 10000.

Re: trajectory calculation and meteo data

For using the ghostview you have installed, check if you set a correct path for the model to find the application. In the GUI, go "Advanced/Configuration Setup/Set Directories" => Capture.PNG The "ftp failed" error was probably due to the firewall blocking the HYSPLIT application. On your window mac...

Re: trajectory calculation and meteo data

Ghostview is used to open figures (generated by HYSPLIT) that are in postscript format. The gsview32.exe is available on the software's website: https://gsview.software.informer.com/5.0/ For downloading the met data from ARL's ftp site, what gads1 file were you trying to get? An alternative way is t...

Re: HYSPLIT Parallel mode installation

The executable running with multiprocessor is hycm_std, not hysc_std (this is for single processor). You will need to modify the Makefile in the exec directory to generate it. There are answers in the forum that may be helpful to you:

Re: Cluster analysis

You can install the HYSPLIT model on your PC (or Mac, or Unix machine) that will give your flexible ways to set up the model for your application. The instruction for installing and running the model are available on the tutorial on the web: https://ready.arl.noaa.gov/documents/Tutorial/html/index.h...

Re: converting multiple wrf output files to arl

Are you able to process the WRF file containing data for 6 hours now?
For running arw2arl for a multiple-time-step file, you need to specify the time period. The program will process all the time steps in the file.

Re: Extract GDAS 1° data

You may consider making a script to download the gdas1 data through the ftp://arlftp.arlhq.noaa.gov/pub/archives/gdas1/ and use a program "xtrct_grid" (in exec directory) to subset the original file (global) to your region of interest. This will reduce the file size. In the script for running "xtrct...

Re: converting multiple wrf output files to arl

When you merge ARL formatted files, make sure it was done orderly.
Use "chk_times" to check if all the time steps in the file are in a correct time sequence.

Re: converting multiple wrf output files to arl

Process WRF output files individually and then use "cat" to merge all the ARL formatted files together.

Re: CAPTEX example IC/BC data

Please check the starting time of the trajectory calculation in the CONTROL file. It seems to be set to 17 UTC. But your WRF run was only for 6 hours. The trajectory calculation did not started at all that there was no value for HYOLAT and HYOLAN. For running trajectory, HYCSUM (concentration) shoul...
