This wiki provides information on how to run Trajpy version 2.0! Trajpy v2 requires backwards trajectories to be generated by HYSPLIT. If you are unsure how to use HYSPLIT to generate backwards or archived trajectories see the Using HYSPLIT section below.

Downloads and System Requirements

You need to have Python 2.7 installed onto your machine.

You must have internet access.

Using HYSPLIT

The trajectory output files should then be saved with a .csv filename extension. These output files should then be put into the same directory as Trajpy-v2.py. Moreover a separate text file is required that has the number of output files as its first line and the name and filename extension of the trajectory output files as each subsequent line.

Using Trajpy v2

Once you have your trajectories (they are all in the same directory, have their file names in a text file with the number of trajectory data dump files as the first item in this text file) you can use Trajpy version 2.0.
