Could SST be used as a proxy for lower-cloud temperature via some empirical 
relation?

The way it was once explained to me by Frank Carsey is that NCEP reanalysis does 
not explicitly resolve lower Arctic clouds in their boundary layer formulation. 
  So their "surface" radiation does not "reach" the surface.
