Hello, I have two different materials, wood and iron in two different environments. I have both the wood and iron temperature, respectively Tw, and Ti. I also know their emissivities, Ew, and Ei. What I want to know is the temperature of the iron if it was wood (i.e. if its material was wood but standing in a different environment from the real wood)? Does the solution have to do with the brightness temperature Tb whose relation with the real surface temperature Ts and emissivity E is: Tb=E(1/4) x Ts ?
