I have run WRF on two nested domains using FNL metdata as input. I wanted to combine the output from the two domains and the FNL data to use as input for HYSPLIT. The idea was that the FNL data would be used outside of the WRF domains. First I converted the FNL files from GRIB2 to GRIB1. Then I conv...

Thank you for the quick response! Are you saying that for each trajectory, 3 hours offset from each other, they are all the same trajectory? That is not right. The output file should have all the date/times and trajectory endpoints for the 56 trajectories. No, the trajectories seem to be mostly corr...

I am trying to run multiple trajectories in time backwards from the same endpoint location using GDAS 0.5 degrees data. The trajectories run for 96 hours each and are offset by 3 hours from each other. The endpoints in each file span over 7 days for each run, which gives 56 trajectories in each outp...

Hi! I realize this thread has not been active for a while, but since it my problem is very similar to the one described here I'll give it a try. I am also downloading ERA-Interim grib data from ECMWF and trying to use them in HYSPLIT by means of the included ERA->ARL conversion tool. This seems to w...
