I’m learning HYPLIT trajectory model and have a question need your help. After running a trajectory frequency display, I can get a trajectory frequency plot. My question is can I get the data of the result so that I can plot the trajectory by myself use other software?
Many thanks in advance for your help!

Re: Trajectory frequency plot
The output of the trajectory frequency program is a binary file (tfreq.bin) in the same format as the binary concentration output and is written to the /working directory. You can find more details about this using the help file on your PC.

Re: Trajectory frequency plot
Hello,
I also have some difficulties of trying to execute trajectory frequency plot display. I ran daily trajectory from March 8 2013 to April 1-9 2013 and I continued to display execution step, but after I hit "execute display" button, following simulation log appeared

This is the message appeared on the simulation log:
"gridding: trajfreq -ftfreq.bin -g1.0 -INFILE -r0 -s0: 99999
ERROR: supports only one trajectory per input file"
I use Acer Aspire 5310 2 GB DDR2 Windows 7 Ultimate 32 bit OS.
Could anyone please help me solve this problem?
Thank you in advance.

Re: Trajectory frequency plot
The trajectory frequency program is saying there can only be one trajectory per input (tdump) file. Did you run trajectories from 3 levels? If so, you need to re-run with one level only.

Re: Trajectory frequency plot
The error message is implying there is more than one trajectory in a tdump file. Is that the case? For example multiple starting heights. The frequency program can only handle one trajectory per tdump file.
