Can anyone help with this question I have been set? Any guidance really
"Describe how one might measure the absorbtivity of a flat surface for a)
solar radiation and b) infrared radiation, given the knowledge of the
temperature of the surface and an instrument which is capable of measuring
irradiance. (Assume that measurements can be taken sufficiently close to the
ground so that atmospheric effects are negligible).
Any help really appreciated.
Thanks in advance,

You know how to use a search engine. Search for web pages that include
absorptivity and irradiance. See if you can find a correlation between
incident energy and the temperature of the surface (or change in
temperature of a surface with time). It may also involve assumptions about
the emissivity of the surface.
