The Gassy Messenger.
This greenhouse effect definition is developed and argued from the following experiments or theoretical claims (and others).
1. The 1859 Tyndall experiment: which uncovered and determined specific atmospheric gases as IR 'absorbent', now known as the greenhouse gases;
From these experiments and demonstrations a climate axiom is formed, the greenhouse effect.
This axiom begs the question: if oxygen and nitrogen are non-greenhouse gases because they have no IR heat ‘blocking’/ absorbing signature, then how is it that the atmosphere is warm at all?
In this (following) entry I shall go through each experiment, one by one, and show that the assumption is wrong, and that each experiment is either wrong, misinterpreted or misattributed. I shall conclude that the (total) atmosphere is made up of only Greenhouse gases – i.e. that oxygen and nitrogen are also heat absorbent. I will show that CO2 is thermally typical, and not at all special - and restore the textbook sea breeze explanation (not that it had changed).
1. The 1859 Tyndall experiment: IR spectroscopy
1.1 Limitations of IR detectors
To cover this new knowledge these limitations, all IR measuring instruments come with an operating manual, that are readily available to read on the Internet. There are also training videos such as the one below on IR camera's and transparency.
1.2 The Tyndall / Dr Stewart IR thermopile experiment
2. N2 and O2 have no dipole, so they are not greenhouse gases.
Yes N2 and O2 are both transparent to IR spectroscopy, but this fact it begs the question (as stated above): how can the atmosphere be warm if 98% of it (N2 and O2) are not IR (heat) ‘absorbent'? How can N2 and O2 be non greenhouse gas, yet they have a heat capacity coefficient?
Something must be wrong with this conjecture.
2.1 Raman Spectroscopy
Raman spectroscopy is well explained in the following clips. I suggest you play them more than once to yourself as they are very insightful and offer perfect solution to the dark climate paradox.
2.2 N2 and O2 Raman Spectroscopy
Another image found is the below (Fig. 18) showing again the 1556 O2, and other peaks at higher wavelengths along the spectrum.
From these images it can be concluded that N2, and O2 (and other gases) are infrared opaque or absorbent, and are too greenhouse gases.
To verify that the above observation is rational, and predictable a cause or explanation to these 'peaks' should be sourced. To do this I simply had to show the vibration mode for both N2 and O2 are symmetrical. As the quote said at the top of this section said 'Nitrogen (N2) is symmetrical AND made of identical atoms' I had part of an answer, but with another google search I found this direct to my question academic reference: Chemistry 362 Dr. Jean M. Standard
It should be noted that the very fact that Nitrogen (N2) is symmetrical AND made of identical atoms is the reason it is transparent to IR spectroscopy: it is symmetrical by nature, and so will never show up, as a law of physics, even in part, like other molecules such as CO2 .
3. CO2 heat camber experiments: which demonstrate how the gas of CO2 temperature rises faster than 'air', when in isolation, and when heated;
In brief: these experiments demonstrate CO2 's relatively low heat capacity. These experiments should be conducted with a hypothesis testing the heat capacity of CO2 compared to air and rising temperatures.
4. CO2 ‘s molecule structure: explanations suggesting it is the molecule structure (internal degrees of freedom) that determines the heat trapping ability of CO2.
In brief, this claim is halted by the following fact: '...the resulting specific heat capacity is a function of the structure of the substance itself. In particular, it depends on the number of degrees of freedom that are available to the particles in the substance, each of which type of freedom allows substance particles to store energy. http://en.wikipedia.org/wiki/Heat_capacity
5. The far infrared re emission (of heat energy).
In brief, there is relatively low (heat) energy the far infrared.
