North American solution for Barrow winter
The North American solution for Barrow winter is shown below in red italic. It fails handily, and confirms our long-held conclusions that North American is not a major sources of Arctic haze, at least at the surface.

We begin by repeating the figure for step 2 so as to show the justification for pursuing a North American solution. It is weak, and should give poor results.
Step 3 adds Akron, with the highest of the North American F-ratios. It produces a fit of 3.26, which is still poor.
Step 4 adds the highest remaining NA source, Sudbury. It improves the fit modestly, to 2.69.
Step 5 adds the bet remaining NA source, West Point. The fit improves modestly, to a still-unacceptable 2.34.
Step 6 adds the type-source DCref (refuse incineration), which again improves the fit modestly, to 1.92. The North American thread stops here with a poor fit. Again note the high Arctic F-ratios waiting in the wings.
