For the trajectories, there is no difference between the two versions, so download the unregistered version. And yes, you need to install the graphical utilities before installing HYSPLIT.

Unfortunately we do not have that option available on the web-version of HYSPLIT. We will consider adding it in the future.

Re: Why do web-based and installed HYSPLIT create different results?

If you set the maximum height of the model on the PC to 15240.0 you will get the same results as the web version. HYSPLIT uses this number to scale the internal levels of the model and because your trajectories crossed some weather discontinuity in northern Italy, the small difference in the levels ...

You might also want to do a reset on the main page of PC HYS...

The extra meteorological file for the 26th is added on the web version so that users can run back trajectories starting late on the 25th. HYSPLIT needs the extra file so that it can interpolate meteorological data for the last few hours of the day. You ran 4 trajectories from the same location and a...
