Hey all,

Trying show back trajectories at one location from the same period (day/month) over the last 10 years.

Is it possible to run a frequency model for multiple non-sequential days? If not, is there a simple way to combine trajectory or frequency runs afterwards? If downloading data, what method would you recommend to add the trajectories together manually?

Any suggestions are helpful-

I am not quite clear on your question.

The trajectory frequency program will run on the endpoints files listed in the file INFILE (see https://www.ready.noaa.gov/documents/Tu ... _freq.html) whether they are sequential days or not.

For example if you run trajectories for every days in June only (no other months), 2011-2020, but you want a frequency plots of June 1-7 only, use a text editor such as Notepad to make the INFILE with the dates June 1-7 or all those years.
