Temperature Correction: Get Accurate Wall Surface Temperature

AI Thread Summary
The discussion centers on correcting temperature readings from an ibutton sensor attached to a stainless steel surface exposed to sunlight. The user seeks methods to account for the impact of solar radiation on the temperature data collected over four months. Suggestions include shading the sensor to compare readings in sunlight versus shaded conditions, as well as analyzing data from cloudy days compared to clear days. The user has access to average irradiance, specific heat values for stainless steel 305, and concrete wall temperatures. Effective correction methods are essential for accurate wall surface temperature assessment.

Dear All,
I have collected temperature data for a period of about 4 months with a device called ibutton attached to the surface of a concrete wall. My problem is the button is made of Stainless steel 305 and exposed to sunlight.
I am interested in obtaining the wall surface temperature and at the same time i know the effect of the sunlight would affect temperature readings (if i am not wrong).
does anyone know or have an idea on how i can correct these readings if i have to?
 
Science news on Phys.org
Data available to me at the moment are: average irradiance of the location, specific heat of the stainless steel 305 and that of the concrete wall (including temperature values)
 
Can you shade the temperature sensor and compare readings in and out of sunlight? Or can you compare readings on cloudy days vs clear days?

Vídeo: The footage was filmed in real time. The rotor takes advantage of the thermal agitation of the water. The agitation is uniform, so the resultant is zero. When the aluminum cylinders containing frozen water are immersed in the water, about 30% of their surface is in contact with the water, and the rest is thermally insulated by styrofoam. This creates an imbalance in the agitation: the cold side of the water "shrinks," so that the hot side pushes the cylinders toward the cold...
