Hello,
I just began running hysplit ensemble cases but I am running into a few issues.
1. I can get the serial ensemble (hycs_ens) to run fine but when I try to run the parallel version (hycm_ens) I get a signal 15 error. Apparently there is an issue reading some input file. I got a similar message when running hycm_std but I think it was more to do with how I was submitting jobs rather than my submit script. Below is my submission script for the parallel ensemble run:
#PBS -q default
#PBS -N parallel_ensemble
# request X processes (X = nodes * cpus)
#PBS -l nodes=4:ppn=2
# request wall time
#PBS -l walltime=04:00:00
# PBS output files
#PBS -o $PBS_JOBNAME.OUT
#PBS -e $PBS_JOBNAME.ERR
echo "script running on host `hostname`"
# directory where qsub started
cd $PBS_O_WORKDIR
echo "$PBS_NODEFILE"
cat $PBS_NODEFILE
echo `pwd`
rm -f MESSAGE.???
rm -f step2.sh
# Run HYSPLIT
for mem in 1 9 17 25
do
time mpirun -np `wc -l < $PBS_NODEFILE` -machinefile $PBS_NODEFILE /share/huina/akp4221/hysplit/trunk/exec/hycm_ens $mem >>step2.sh
done
2. Once I get the output I'm not sure how to process it to get the most out of the data. I found Roland Draxler's paper on ensemble dispersion modeling but I can't figure out how to create EP or CP plots from the given output files. I assume it is simple once you run conprob but there is no documentation I have found to expound this process. The only ensemble executable I found was ensplot which produces a very noisy scatterplot that is honestly hard to look and definitely not something that one can show to the public.
Mahalo!

Andre,
Please check up the following link:

It gives an example of how to process the output created by an ensemble run.
