Yesterday, 17 September, people around Greater #VictoriaBC noted a thick plume of smoke passing overhead. The fire was close enough that particles of soot and ash were still falling out of the plume (image of my patio umbrella below).
The smoke blew from south of us and through the morning moved from west to east across sky. By 12:00 it was no longer affecting us. The image attached shows the plume as seen by the Terra satellite at 10:17. On the right is a graph of the incoming short-wave radiation showing the 16th (clear sky) and the 17th, smoky, then patchy clouds.
Between 06:00 and 12:00 the smoke reduced the energy that reached the surface down to 60% of the clear sky value.
Particulate concentration observations from the Purple Air network suggest that, fortunately, the plume stayed above us. It wasn't very high above though. Sites like the one on BWC at UVic show higher concentrations than those at the surface.

@edwiebe Good grief! Do we know what the source was? Forest fire?

@mykl Yes, wildfire.
