ConclusionsEvidence for long-range transport of smoke over Florida
The dust model shows dust at the right altitude on July 29Not enough dust to match the lidar extinctionSurface concentrations are too low
Turning off wet removal makes the rest of the simulation look worse
Increasing the source or adding a coastal source can help, but what’s the evidence for this?
Possibly the wind fields are not right..?

Future DirectionsFurther evaluation of the sea salt source
Include smoke aerosol in the simulation for the CF time frame
Try another wind source for the dustemissionstransport
Further investigate the removal mechanisms at play here
