I tried to check the top of the domain with the following way: 1) run the profile.exe: cmd C:\hysplit4\exec>profile.exe –dc:\hysplit4\working\ -f20161025_gdas0p5 –y49 –x15 –t3 where the options: -d is Input metdata directory name with ending \ -f the input metdata file name -y the latitude (I used t...

According to the HYSPLIT4 Users' Guide the default value of the top of the model is 10000, but it can set if the model domain exceed. How can I check if the default value is suitable and we can trust in the result?
Thank you for your response in advance!

Thank you! You are right! It caused the differences.

I attached the Setup and Control files.

The SETUP.CFG and the CONTROL files are the same (except the top of the model). I attached the MESSAGE files. The Message files are different. I do not know which one is reliable.

Dear glenn.rolph, Thank you for your response! I run again the back trajectory with two trajectory from the same location with two different heights in web and I also run the back trajectory with same set up (using meteorology in 26th as well) on my PC but the results are still different. I do not k...

Dear All, I registered and intalled HYSPLIT-4 and run a -197 hours back trajectory from two sources. I used GDAS0p5 meteorology from 17.10.2016 to 25.10.2016. The initial time of back trajectory was 2016.05.25 17:00. I also run this back trejectory with same parameters (initial time, meteorology, en...

Thank you very much for your reply. I found the mistake. I checked the MESSAGE file as you suggested and I got to know that the .grib files are not found. After I copied the .grib files into the working directory (hysplit/working) the program found the files and could convert them.

Dear All, I use HYSPLIT_4 on Windows 7 OS. I would like to convert ERA-Interin (0.75X0.75) resoultion files in Europe. The upper air 3D file contains the variavles (geopotential, temperature, uvelocity, v-velocity, w-velocity, and relative humidity) in 37 pressure levels, 2D file contains the surfac...
