14. Backtrajectories for organics OCf on the day of the Quebec smoke, 2002-07-07; b. Backtrajectories for a sulfate event 2002-07-30 Trajectories with receptor SO4 concentration near 0 are shown as thin blue line. Trajectories with receptor SO4 concentration over 20 ug/m3 are shown as heavier red lines. This color/thickness coding of trajectories conveys, in an intuitive way, the transport direction where ‘dirty’ and ‘clean’ air is coming from on a given day The map zoom rectangle was reset (by the magnifying glass icon), to cover the Eastern U.S. only In this mode, the list of receptor locations include all the sites that are in the zoom rectangle of the map view. Moving the location cursor in the map view will not change the selected trajectories.

18. Seasonal transport, high and low percentile during summer (JJA) at GRSM Aggregations for specific seasons are intended to illustrate the transport conditions during differences of these seasons. The seasonal (actually monthly) filter is always imposed in addition to the other filter conditions (loc_filter, time_filter). The specific month to be used for the aggregation can be selected in the main query form accessible through the Q-button

29. Transport of Different Species for Everglades, FL

30. Transport of SEf to Different Sites

31. Transport of NO3f to Different Sites

32. Sulfate Transport to BIBE, GRSM, and LBYR
