  1. Hydrocarbon Ratios for Q-L Segments of the DC-8, Intex-B By: Andy Latto

  2. Source Locations were determined by examining gridded sources for ARCTAS (Lat., Lon., Emmissions Grid. • Time from source was determined by the Q-L backward trajectories most recent encounter with a source, since most trajectories encountered more than one source over 10 days.

  3. There were a wide variety types of encounters with sources, although source locations were mostly E. Asia • I believe that height that the air parcel takes over a source region has an effect on the influence of the pollutants on that parcel • Many trajectories that passed above 400 mb over the sources were those that had lower pollution levels when they reached the DC-8 • Legs have been re-numbered due to some being defined by too few flight minutes. A total of 11 Q-L legs remain. • The spreadsheet containing all data used for these charts is attached to this email.

  4. Unaveraged Plots of Hydrocarbon Ratios 1 point represents a cannister measurement. All Q-L Legs 1,2, and 4 days are represented

  5. Legs 2,4,5,8,and 11 had CO values relatively higher than the Background

  6. Legs 2,4,5,8,and 11 had CO values relatively higher than the Background

  7. Legs 2,4,5,8,and 11 had CO values relatively higher than the Background

  8. Legs 2,4,5,8,and 11 had CO values relatively higher than the Background

  9. Legs 2,4,5,8,and 11 had CO values relatively higher than the Background

  10. Legs 2,4,5,8,and 11 had CO values relatively higher than the Background

  11. Averaged Hydrocarbon Plots Each point represents a Q-L Leg. All 11 Q-L legs, 1,2, and 4 days are shown.

  12. Legs 2,4,5,8,and 11 had CO values relatively higher than the Background

  13. Legs 2,4,5,8,and 11 had CO values relatively higher than the Background

  14. Legs 2,4,5,8,and 11 had CO values relatively higher than the Background

  15. Legs 2,4,5,8,and 11 had CO values relatively higher than the Background

  16. Legs 2,4,5,8,and 11 had CO values relatively higher than the Background

  17. Legs 2,4,5,8,and 11 had CO values relatively higher than the Background
