Exercise #6




  • Problem #1 - The trajectory clustering tutorial assumed the release would be from Dayton, Ohio. The other tracer release point was Sudbury, Ontario (46.62N 80.78W). Would Sudbury have been a better selection for September?

  • Hint - Retrieve traj_freq_control.txt, change the starting location to Sudbury, and then run the daily trajectories and determine the optimum number of clusters.

  • Solution - clusplot.ps. Does the three-cluster solution look any better?

  • Problem #2 - Is the 600 m release height realistic?

  • Hint - Rerun the calculation using a 10 m AGL release height.

  • Solution - The result is not that different.
