HYSPLIT Forum: hysplitbbs.arl.noaa.gov

Hello,
I am running hysplit on linux using the example .sh script given in the tutorial. I would like to have back trajectories extend back multiple days, which requires more than one input file. How should the script be modified in order to do this? I tried to add in another line for data but when running, I get an error. I also tried changing the 1 to a 2 two lines above where the file names are given, as seen below.

Any help would be appreciated! Thanks!

# set up control file for dispersion/concentration simulation

echo "$syr $smo $sda $shr " >CONTROL
echo "3 ">>CONTROL
echo "$olat $olon $lvl1 ">>CONTROL
echo "$olat $olon $lvl2 ">>CONTROL
echo "$olat $olon $lvl3 ">>CONTROL
echo "$run ">>CONTROL
echo "0 ">>CONTROL
echo "$ztop ">>CONTROL
echo "2 ">>CONTROL
echo "$MET/ ">>CONTROL
echo "$data ">>CONTROL
echo "$data2 ">>CONTROL
echo "$OUT/ ">>CONTROL
echo "tdump ">>CONTROL

You are on the right track! You just need to add another line above the second meteorological data file for the directory. Each new meteorological file must also have a directory line associated with it.

I have it working now! Thank you so much!
