The solar spectrum of the sun consists of a roughly black body like thermal continuum spectrum, peaking at around 0.5 microns wavelength (plotted on wavelength scale; not wave number), and overlaid
with the Fraunhoffer
lines of either bright atomic
spectral lines, due to elements in the sun, or dark atomic absorption
lines, due to absorption of elements in the solar outer atmosphere.
We know quantitatively, albeit roughly, from the work of Tyndall in the 1850s the extent to which CO2 itself,
with no feedbacks, blocks the passage of thermal radiation; these days we infer this much more precisely from the HITRAN tables of
spectral absorption / emission
lines.
If one were to take the model and plot a curve of emission versus wavelength rather than simply summing up the values (integrating over wavelength), it would show a
spectral curve of a black body at 288.2 k
with the absorption
lines of the atmosphere dipping down to the point where there is a
spectral curve for a lower temperature at which there is emission going on in the wavelength bands associated
with ghg absorption.
Starting
with the surface, each layer attenuates the BB spectrum
with the ghg

Furthermore, on 22 April 1981 Mr. Gilbert Plass wrote that, whilst on the faculty at Johns Hopkins University during that period (1946 - 1955), he became interested in infrared spectroscopy — specifically in regards to pressure broadening of
spectral lines (in explaining radiative transfer in the earth's atmosphere)-- and collaborated
with Mr. John Strong in the above article because the need for [quote] «mathematical methods» [endquote], applicable to water, carbon dioxide and ozone, was obvious to him then.
Has anyone looked for one
with the diligence that early 20th century physicists looked for an explanation of the
spectral lines of gases?
On the other hand, once water is present, its IR
spectral lines overlap
with those of CO2 and make CO2 less potent a greenhouse gas — for the same reason why the temperature dependence on CO2 concentration becomes logarithmic: the previous molecules have already done much of the effect, anyway.
