Re: Daily Runs Backward Trajectories

Please follow the instructions described in the link from my response above. The only change you have to make is instead of running 48 hours forward you run for 48 hours backward. Each individual trajectory will represent a 48 hour back trajectory from the source that you enter in though the GUI.

Re: Parallel version slower than the serial one

OK, that is pretty fast. I would suggest you increase the duration of the runs and see if you notice any difference. Since the parallelization is done over the number of particles, you will not notice any difference with runs that take such a short time. In your runs most of the time is spent readin...
