Question:
How do I calculate and visualize backward and forward trajectories for our air pollution monitoring station on the READY website?

Answer:
Start by going to the HYSPLIT READY website at: https://www.ready.noaa.gov/HYSPLIT.php
  • click on either “run with forecast data” or “run with archived data”
  • choose a dataset that covers your area.
  • enter the lat./lon. of your station in the boxes provided
  • fill out the form for forward or backward, date/time, starting height of trajectories, and model duration.
  • click “Request trajectory”
  • write down your ID number and click “HYSPLIT run results”
  • This page will reload until the run is done (a few minutes)
  • the model is finished without errors when the link to “Trajectory plot” is shown.
