Regarding HYSPLIT and FLEPART

[dmoranz]

Dear colleagues,
There is an article comparison between Hysplit and Flexpart,https://acp.copernicus.org/articles/19/8425/2019/
At least from Amazon rainforest pollutant traces analysis, they worked intensively with HYSPLIT

Thanks for the paper.
The one thing I would note is that it looks like they are comparing an ensemble of HYSPLIT backward trajectories with
backward dispersion from FLEXPART so it's not an apples to apples comparison. It could be they didn't know that HYSPLIT can perform backward dispersion.
