Carl,
If I remember correctly from my work at DUI, the military has conducted
extensive diver thermal studies.  Out of this came the point that with one
measurement, temperatures at various other sites on the body could be
predicted rather accurately.  Granted, there is individual variation, but
sufficient studies have been run to find that the predictions will be pretty
accurate.  I am on good terms with DUI still and from previous talks with
Bob Stinton (VP of Engineering) they were collaborating with the development
of the thermal model for the some deco programs.
Respectfully,
Jay K. Jeffries
