Arctic solution for Barrow winter
We have known for years that aerosol all around the Arctic is similar in winter. Thus Barrow winter aerosol most resembles sites on the other side of the Arctic. That thread is shown below in red italic. Although it reaches a very good fit after three place-signatures, the fit is only nominally better than the European solution (0.66 vs. 0.69), and the solution is composed of receptors rather than genuine sources. Thus it cannot be regarded as a final solution.

We begin by repeating step 2, with only sea and crust chosen. Note how much higher the F-ratios in the Arctic than at the other potential source areas of North America, Europe, and East Asia (mostly Japan/Korea). That is borne out by the thread.
