ability to absorb infrared and NOT re-emit it. CO2 and methane CH4 have very high
absorption/retention rate way beyond ability of individual atoms.

does anybody know if there is a word or measurement that describes that
efficiency at which a substance traps longer waved solar radiation?

For example glass is pretty good at trapping heat, so that may be rated at
100 "Scovillage" units or possibly it could be described as having a
"Maxwell" rating of .5 celsius per second per cubic meter. Polycarbonate
also used for green/glass houses may have a similar values while brick or
other opaque materials would be close to zero. What would the real term
for Scovillage or Maxwell be?
