Quit different backward trajectories with different wind input

Post by chaoyang » February 26th, 2020, 10:27 am

Hi, I'm Glad to use Web-Hysplit for backward trajectories for one site in Morocco. While I got pretty different trajectories with three kinds of wind field inputs of GDAS1, GFS0p25 and Reanalysis. I didn't understand why.
Then I tried to do more comparison and found that sometimes they have almost the same trajectories, while sometimes they were not happy to agree with each other (significantly different).
Do you mind guiding me which wind field data should I use for Morocco? Thank you inadvance.
Have a nice day.
