Appendix 4b. 5-day CAPITAMC Back Trajectories Each page has a map for each of four evenly spaced hours (0, 6, 12, and 18 CST) during a single 24-hour particle sampling period (8am-8am). Red trajectories were generated with MM5 data, blue with EDAS/FNL data. All were generated by the CAPITA Monte Carlo Model.
