It appears to be the albedo-lowering that allows Twp>TDANTE
It makes sense that the XCE wouldn’t do it, because that just scales the energy deposition
But the lower albedo also lowers
the overall temperature a lot
Maybe the effect of the lower albedo on boosting the
relative temperature of the
witness plate is that the lower albedo essentially makes for colder walls. The
hot spots are therefore more important, relatively, and the witness plate view must be more dominated by
hotspots than is the DANTE
view.
