Exterior Glass & Metal Frame Surface Temperatures for 24-hour Period on Clear Day
This graph compares the exterior glass surface temperatures to the exterior metal frame temperature during a 24-hour period. HOBO data spans from 00:07 on Thursday 22 February 2001 through 23:55 on Thursday 22 February 2001. This particular day was generally clear. The exterior glass measurement represents the outer surface of the outer pane of a double glazed window unit. The frame measurement is self explanatory. The 2 sensors are approximately 36" apart.
Comment: The frame temperature was intended to serve as a surrogate for solar radiation; the effect of west sun on the atrium space was a concern of the investigator. High frame (a dark opaque surface) temperatures would indicate direct solar radiation impact. Surprise, surprise! It appears that the glass surface temperature could serve as a surrogate for the frame temperature.
Questions: Why are the surface temperatures of these two radically different materials so similar?
