Noyes includes a graph from a SpaDE concept paper that shows a good-enough-to-deorbit-debris pulse from a weather balloon detonation -- at the same altitude as the debris of 96.6km (though I admit I did not review the original SpaDE paper).
He then includes a brief literature review about the propagation of stable vortices in a wind tunnel (i.e. at sea level).
Using atmospheric model from the SpaDE paper (again, used at 96.6km and which is claimed to be valid down to 30km), plus the wind tunnel vortex data from sea level, Noyes claims that vortices could plausibly remain intact from the surface to orbital altitudes.
Without commenting on the concept in general, I find this argument to be unconvincing. The atmospheric model cannot be applied to the vortex data (or vice versa), so I don't see how we can draw any conclusions from the two together.
