Just spoke with John. He is pretty sure that the radiometers were inadvertently mounted upside down. This explains the pyrgeometers reporting reversed and Rsw.out being large. It doesn't explain Rsw.in being VERY large. Their schedule doesn't allow him to flip them over today, but it is on the list.
While at the site, he also unplugged the offending TP01.aux -- we'll see if data from the other sensors improve. (So far, not for Tsoil.4.4cm, at least.)
