Hey guys, I'm just wondering is it possible to do both: Multiple Trajectories in Space https://ready.arl.noaa.gov/documents/Tutorial/html/traj_ensem.html and Multiple Trajectories in Time Unless I've misunderstood ensemble releases at different heights and not other locations and when I changed the ...

Dear Mark, That is awesome! I have increased the settings and it seems to be working so much better. And looks very similar to Flexpart's production. Thank you so very much for such detaield answers! I think many work collegues will be using Hysplit more now knowing that they can make these trajecto...

Many thanks,

Goign to try that, quick Q:

I've worked out how to change the initial speed but how do you changet he heights as you sugegsted to do?

Mark, I had seen that bit of the documentation but it wasn't till you said it that I saw how to change the grid settings! So thank you very much. Do you have any idea what would cause the plot to have huge gaps-see attached file. I also attached my expected output in my other question (which is same...

Thank you very much, but is there a way to do it with concentrations as supposed to trajectories? As in lots of particles?

See my other question as someone very kindly helped out there.

I think that is the kind of thing I am after (will have to check with supervisor) but this is for a forward trajectory, I followed the same steps again with backward but on the Trajectory>Special Runs>Daily is this running backwards as start day cant be after the end day.

Think found what i want in Ensemble Probability display (under concentration) but it won't run due to a missing file: forrtl: severe (29): file not found, unit 101, file c:\hysplit4\working\fort.101 Any idesas what this file contains or how to obtain it? Couldn't see anything about this on the tutor...

Hello, I was wondering if you could tell me how to integrate over a time period, so it gets the probability of where the air has come from. As supposed to at the moment it seems to produce a picture every 12 hours as a seperate image. Also I have been workign my way through the tutorial and there is...

Dear Sir/Madam I am trying to find out the probability of an air parcel arriving at a particular destination. The timescale’s I am looking at around the two week mark, and so far I have plotted a backtrack trajectory over a similar time period. However, when doing so it gives a probability but durin...
