Re: Particles not wrapping around with global met fields

We're running with the Linux executables.
I re-ran our tests against the latest version 5.3.4, and can confirm that this version does fix the global boundary issue for our experiments.
Many thanks for the quick solution to this problem!

Re: Particles not wrapping around with global met fields

Apologies for any confusion. For GDAS, I'm getting a different particle cut-off at the prime meridian instead of the dateline. Seems to be specific to the dataset being used. Could you confirm if your particles are getting across the 0 degree longitude in your GDAS test? Thanks! We're using the full...

Re: Particles not wrapping around with global met fields

Same issue happens with GDAS1 met data, so this seems to be a general problem with global met fields and HYSPLIT 5.3? Particles hit the "boundary" of the grid, and die.

Particles not wrapping around with global met fields

Running HYSPLIT 5.3.0 back trajectories, with ERA5 global met data encoded with hysplit_metdata and era52arl tools and the default area of 90/-180/-90/180 and grid resolution 0.3. In HYSPLIT, when the particles hit the meteorology longitude bounds (-180), they disappear from the grid. One example of...
