My understanding of this is that the Globe Temperature is actually a function of Air Temp, MRT and the convection (air speed effects.) The MRT is calculable from the temperature of the surrounding surfaces. If the Op Temp calculation includes air temp, MRT, RH, and air speed, then there is no need to ever know Globe Temp.
