Why the effective radiating level (ERL) is always located at the center of mass of the atmosphere & not controlled by greenhouse gas concentrations

The Arrhenius radiative greenhouse effect proponents, having abandoned "back-radiation" from greenhouse gases as the explanation of the greenhouse effect, now claim global warming is instead due to an increase of the "effective radiating height" or "effective radiating level" [ERL] of greenhouse gases in the atmosphere. So the theory goes, an increase of CO2 levels will cause longwave (~15 micron) infrared emissions from CO2 to occur from colder heights in the atmosphere, and since colder blackbodies emit less radiation, more radiation will allegedly be "trapped" by the colder CO2 "blackbody" in the fabled tropospheric "hot spot" & unable to escape to space. 

In contrast, the competing 33C gravito-thermal greenhouse effect of Maxwell, Clausius, Carnot, Boltzmann, Feynman, Poisson, Helmholtz, et al, shows that the "effective radiating level" or ERL is fixed at the center of mass (COM) of the atmosphere.

As we can see in Fig 1a, the observed ERL or "emission level for OLR (Outgoing Longwave Radiation)" global average is right around 500 millibars or 0.49 atmospheres ~ 0.5 atmospheres, exactly at the center of mass of the entire atmosphere as predicted in the HS greenhouse equation below. 

The HS greenhouse equation "triangulates" the geopotential height of the 255K ERL at the center of mass using:

1. The center of mass (COM) of the atmosphere where P=0.5 atmospheres (after density correction), i.e. exactly one-half of the surface pressure
2. The adiabatic lapse rate = -(gravitational acceleration constant g)/(heat capacity at constant pressure Cp)
3. The equilibrium temperature of Earth with the Sun = 255K

all of which are essentially constants in the atmosphere, and without any knowledge of the surface temperature, greenhouse gas concentrations, or Arrhenius "radiative forcing" from greenhouse gases.  

Why use the center of mass of the atmosphere in calculation of the gravito-thermal greenhouse effect? Because the force of gravity by Newton's Second Law is F = ma = mg, and for a system of particles like our atmosphere, one must determine the center of mass in applying Newton's 2nd Law F = mg to the force of gravity. 

Thus, since the height of the ERL is fixed at the COM, and the COM is essentially a constant, the height of the ERL will not change, regardless of greenhouse gas concentrations.

In addition, in the longwave infrared band of Earth’s thermal radiation, the only band in which CO2 absorbs and emits is centered at ~15 microns. The kinetic temperature of the surrounding atmosphere and the CO2 molecules has nothing to do with the fact that CO2 emits at a fixed ~15 microns in the longwave IR due to its fixed molecular structure bending transitions. The entire atmosphere surface to space is warmer than the CO2 “equivalent partial blackbody” fixed band-emitting temperature of 193K at ~15 microns.

Also, absorption followed by emission of a photon by CO2 only takes microseconds, and all the bouncing around at the speed of light between greenhouse gases in the atmosphere only delays the average photon a few milliseconds on its way from the surface to space. Thus, the only "slowing of cooling" or "heat trapping" by CO2 absorption/emission is a few milliseconds and easily reversed and erased over a 12 hour night. 


Addition of more CO2 increases the few milliseconds delay by adding a few more milliseconds, but once again is easily reversed and erased over a 12 hour night.

More importantly, increased CO2 increases radiative surface area, which increases radiative loss to space. That’s why increased CO2 cools the stratosphere through thermosphere, and troposphere as well as I’ve shown.

And even more importantly, the probability of CO2 transferring heat by collisions with N2/O2 in the troposphere is about 2 orders of magnitude higher than emitting a photon, which increases convective cooling.

An earlier post also provides nine additional reasons why the effective radiating level (ERL) is always located at the center of mass of the atmosphere & not controlled by greenhouse gas concentrations.

Thus, the false notion that global warming is instead due to an increase of the "effective radiating height" or "effective radiating level" [ERL] of greenhouse gases in the atmosphere is effectively disproven.

The HS greenhouse equation and quick & dirty explanation below, followed by the derivation from first principles:
The "Greenhouse Equation" calculates temperature (T) at any location from the surface to the top of the troposphere as a function of atmospheric mass/gravity/pressure and radiative forcing from the Sun only, and without any radiative forcing from greenhouse gases. Note the pressure (P) divided by 2 in the greenhouse equation is the pressure at the center of mass of the atmosphere (after density correction), where the temperature and height are equal to the equilibrium temperature with the Sun and ERL respectively.

http://hockeyschtick.blogspot.com/2014/11/quick-and-dirty-explanation-of.html

We will use the ideal gas law, 1st law of thermodynamics, Newton's second law of motion (F = ma), and well-known barometric formulae in this derivation to very accurately determine Earth's surface temperature, the height in the atmosphere at which the effective equilibrium temperature of Earth with the Sun is located, and show that this height is located as expected at the center of mass of the atmosphere on Earth and Titan.

We will show that the mass/pressure greenhouse effect theory can also be used to accurately determine the temperatures at any height in the troposphere from the surface to the tropopause, and compute the mass/gravity/pressure greenhouse effect to be 33.15C, the same as determined from radiative climate models and the conventional radiative greenhouse effect theory. 

1. Conservation of energy and the ideal gas law

We will start once again with the ideal gas law 

PV = nRT (1)

an equation of state that relates the pressure P, volume V, temperature T, number of moles n of gas and the gas law constant R = 8.3144621 J/(mol K)

The properties of gases fall into two categories: 

1. Extensive variables are proportional to the size of the system: volume, mass, energy
2. Intensive variables do not depend on the size of the system: pressure, temperature, density

To conserve energy (and to ensure that no radiative imbalances from greenhouse gases are affecting this derivation) of the mass/gravity/pressure greenhouse effect, we assume

Energy incoming from the Sun (Ein) = Energy out (Eout) from Earth to space

Observations indeed show Ein = Eout = 240 W/m2 (2)

which by the Stefan-Boltzmann law equates to a blackbody radiating at 255 K or -18C, which we will call the effective or equilibrium temperature (Te) between the Sun and Earth. As seen by satellites, the Earth radiates at the equilibrium temperature 255K from an average height referred to as the "effective radiating level" or ERL or "effective radiating height."

2. Determine the "gravity forcing" upon the atmosphere

Returning to the ideal gas law above, pressure is expressed using a variety of measurement units including atmospheres, bars, and Pascals, and for this derivation we will use units in atmospheres, which is defined as the pressure at mean sea level at the latitude of Paris, France in terms of Newtons per square meter [N/m2]

Newtons per square meter corresponds to the force per unit area [or "gravity forcing" upon the atmospheric mass per unit area of the Earth surface]. 

Now let's determine the mass of the atmosphere above one square meter at the Earth surface:

By Newton's 2nd law of motion equation, force (F) is 

F = ma  (3)   where m = mass and a = acceleration

As we noted above, the atmospheric pressure is a force or forcing per unit area. The force in this case is the weight (note weight is not the same as mass and is in physical definitions of mass, length, time-2) or mass of the atmosphere times the gravitational acceleration, therefore

F = mg  (4) where g is the gravitational constant 9.8 m/s2, i.e. the acceleration due to gravity in meters per second squared.

If we assume that g is a constant for the entire column of the atmosphere above the 1 meter2 area (A) we obtain

m = PA/g = (1.0325 x 10^5 N/m2 )(1 m2 )/(9.8 m/s2 ) = 1.05 x 10^4 kg

thus, the weight of the atmosphere over 1 square meter of the surface is 10,500 kilograms, quite a remarkable gravitational forcing upon the atmosphere.

If m is the mass of the atmosphere and g is the gravitational acceleration, the gravitational force is thus

F = mg (4)

The density (p) is the mass (m) per unit Volume (V), thus,

p = m/V

SI units of pressure refer to N/m2 as the Pascal (Pa). There are 1.0325 x 10^5 Pa per atmosphere (unit). 

Starting again with equation (3) above

F = ma  (3)

F = mg  (4)

F = (PA/g)g = PA  (5)

P = F/A = mg/A = phAg/A = phg (6) 

where 

h=height along either a gas or liquid column under pressure or gravity field
g = gravitational constant
p = density = mass/volume

3. Determine the atmospheric pressures from gravitational forcing, and the height of the effective equilibrium temperature (ERL)

Now we will determine the atmospheric pressures in a gravitational field using (6) above

First let's determine the pressure at the ERL since the temperature must equal the equilibrium temperature of 255K at the ERL.

The pressure is a function of height 

P(h) = ρgh (7)

and the change in pressure dP is related to the change in height dh by 

dP = -ρg dh (8)

The minus sign arises from the fact that pressure decreases with height, subject to an adjustment for density which changes with height. We will determine this adjustment from the ideal gas law. The density is 

ρ = nM/V  (9)

where n is the number of moles, M is the molar mass, and V is the volume. We can obtain n/V from the ideal gas law: 

n/V = P/RT (10)

thus 

ρ = MP/RT  (11)

We can now substitute the density into the pressure vs. height formula:

dP = -(MPg/RT)dh  (12)

 dP/P = -(Mg/RT) dh  (13) (the first integral is from 1 to P, second from 0 to h)  

ln(P) = -(Mgh/RT)  (14)

P = e^-((Mgh/(RT))  (15)

We will now determine the height (h) at the ERL where the temperature = the effective equilibrium temperature = 255K, and without use of radiative forcing from greenhouse gases.

Plugging in numbers of M = 29 grams/mole (0.029 kg/mole) as average molar mass for atmosphere, g = 9.8 m/s^2, Pressure = 0.50 atmospheres at the approximate center of mass of the atmosphere, R=8.31, and T=Te=255K effective equilibrium temperature we obtain:

0.50 atmosphere P at the ERL= e^-((.029*9.8*5100)/(8.31*255))

So the height of the ERL set by gravity forcing is located at 5100 meters and is where T=Te=255K and pressure = 0.5 atmospheres, right at the center of mass of the atmosphere as we predicted from our gravity forcing hypothesis. 

4. Determine the temperatures at any location in the troposphere, and the magnitude of the mass/pressure greenhouse effect

Now that we have solved for the location of the ERL at 5100 meters, we can use the adiabatic lapse rate equation to determine all troposphere temperatures from the surface up to the ERL at 255K and then up to the top of the troposphere. The derivation of the lapse rate equation from the ideal gas law and 1st law of thermodynamics is described in this post, thus will not be repeated here, except to mention that the derivation of the lapse rate 

dT/dh = -g/Cp where Cp = heat capacity of the atmosphere at constant pressure

is also completely independent of any radiative forcing from greenhouse gases, greenhouse gas concentrations, emission/absorption spectra from greenhouse gases, etc., and is solely a function of gravity and heat capacity of the atmosphere. 

Plugging the average 6.5C/km lapse rate and 5100 meter or 5.1 km height of the ERL we determine above into our derived lapse rate equation (#6 from prior post) gives

T = -18C - (6.5C/km × (h - 5.1km)) 

Using this equation we can perfectly reproduce the temperature at any height in the troposphere as shown in Fig 1. At the surface, h = 0, thus temperature at the surface Ts is calculated as

Ts = -18 - (6.5 × (0 - 5.1)) 

Ts = -18 + 33.15C (gravity forced greenhouse effect)

Ts = 15.15°C or 288.3°K at the surface

which is exactly the same as determined by satellite observations and is 33.15C above the equilibrium temperature -18C or 255K with the Sun as expected.

Thus, we have determined the entire 33.15C greenhouse effect, the surface temperature, and the temperature of the troposphere at any height, and the height at which the equilibrium temperature with the Sun occurs at the ERL entirely on the basis of the Newton's 2nd law of motion, the 1st law of thermodynamics, and the ideal gas law, without use of radiative forcing from greenhouse gases, nor the concentrations of greenhouse gases, nor the emission/absorption spectra of greenhouse gases at any point in this derivation, demonstrating that the entire 33C greenhouse effect is dependent upon atmospheric mass/pressure/gravity, rather than radiative forcing from greenhouse gases. Also note, it is absolutely impossible for the conventional radiative theory of the greenhouse effect to also be correct, since if that was the case, the Earth's greenhouse effect would be at least double (66C+ rather than 33C). 

In essence, the radiative theory of the greenhouse effect confuses cause and effect. As we have shown, temperature is a function of pressure, and absorption/emission of IR from greenhouse gases is a function of temperature. The radiative theory tries to turn that around to claim IR emission from greenhouse gases controls the temperature, the heights of the ERL and tropopause, and thus the lapse rate, pressure, gravity, and heat capacity of the atmosphere, which is absurd and clearly disproven by basic thermodynamics and observations. The radiative greenhouse theory also makes the absurd assumption a cold body can make a hot body hotter,disproven by Pictet's experiment 214 years ago, the 1st and 2nd laws of thermodynamics, the principle of maximum entropy production, Planck's law, the Pauli exclusion principle, and quantum mechanics. There is one and only one greenhouse effect theory compatible with all of these basic physical laws and millions of observations. Can you guess which one it is?

  1. MS,

    It does seem clear to me that for an atmosphere suspended off a surface against the force of gravity in hydrostatic balance the average effective radiating height would be at the centre of mass.

    However, there are many varied atmospheric constituents that have radiative capability and there is no reason why each should not have its own discrete effective radiating height.

    Nonetheless, if an atmosphere is to be retained the average effective radiating height must be at the centre of mass.

    That implies that if one atmospheric constituent changes in quantity then any change in its effective radiating height must be offset by an equal and opposite change in the effective radiating height of one or more of the other atmospheric constituents.

    In my humble opinion any radiative capability off the surface must reduce surface radiation to space so that any changes in the radiative capability of atmospheric constituents simply swap thermal effects between themselves or with the surface to retain atmospheric equilibrium.

    Changes in convection are the mechanism whereby the effective radiative heights of individual atmospheric constituents negate or neutralise any radiative imbalances caused by those constituents:

    http://www.public.asu.edu/~hhuang38/mae578_lecture_06.pdf

    The result is that surface temperatures below atmospheres and the average temperature at every height off the surface can be calculated simply by reference to top of atmosphere insolation and surface atmospheric pressure caused by atmospheric mass subjected to the force of gravity.

    That seems to accord with observation of the various planetary atmospheres that have been investigated to date.

      Yes agreed, and we're already up to the only 8 rocky planets in the solar system that have sufficient data to prove that hypothesis!

      In contrast, the Arrhenius GHE theory fails miserably in trying to explain the GHE on Earth, Mars, and Venus!

  2. On reflection I’m not so sure of the centre of mass aspect.

    If there is no radiative capability in an atmosphere the radiation to space all comes from the surface yet the atmosphere remains in hydrostatic balance.

    Earth’s surface would still be at 288K and 255K would still get out to space but it would all be coming from the surface so the effective radiating height would be the surface and not the centre of mass.

    I think the answer lies in separating the effective radiating height from the processes of conduction and convection such that the mass of the atmosphere is supported by conduction and convection with only the surplus radiating out.

    Radiative capability within an atmosphere does raise the effective radiating height off the surface proportionately to the radiative efficiency of the atmosphere but appears to be unrelated to the centre of mass.

    Convection would then be the process that reconciles any thermal imbalance arising as a result of the effective radiating height moving up from the surface.

  3. Could it be that convection adjusts as necessary to arrange that the temperature at which radiation is emitted to space is found at the centre of mass regardless of where that radiation actually departs from ?

    1. The 255K "ERL" is located near the center of the 68K tropospheric temperature gradient at the center of mass. From the 255K ERL to surface there is a 33K "enhancement" and from the ERL to tropopause an even larger -35K anti-greenhouse effect.

      All the gravito-thermal effect does is re-distribute the heat from the Sun more toward the surface and less to the upper troposphere in comparison to the 255K ERL.

      Delete
    2. The "ERL" is just an "average" emitting level. If you look at the OLR spectra you'll see the linear lapse rate temperatures line up perfectly with the spectra, indicating the Arrhenius believers have confused the cause with the effect.

    3. I think we can clarify the matter by refining the terminology.

      There are numerous actual emitting levels each corresponding to a single atmospheric constituent with radiative capability. They can be at any height and if the atmosphere were radiatively inert there would be one such level at the surface

      There is an average emitting level found by combining all the actual emitting levels.

      There is an effective emitting level where the atmosphere is at the temperature required to achieve observed radiation to space. For Earth that temperature is 255K and the effective emitting level as so defined is found at the centre of mass.

      Since all atmospheres emit some radiation there is a possibility of creating radiative disequilibrium but that is negated by convective adjustments as confirmed here:

      http://www.public.asu.edu/~hhuang38/mae578_lecture_06.pdf

      profile could be unstable;
      convection restores it

    4. "There is an effective emitting level where the atmosphere is at the temperature required to achieve observed radiation to space. For Earth that temperature is 255K and the effective emitting level as so defined is found at the centre of mass."

      All true, but more importantly the 255K ERL is the equilibrium temperature of the Earth with the Sun, thus energy is conserved Confirmed by satellite observations, the blackbody temperature of Earth seen from space is 255K, exactly the same as the the equilibrium temperature of Earth with the Sun as calculated by the S-B Law.

    5. Yes.

      When the atmosphere first rose off the ground then (assuming current mass, gravity and insolation) the Earth's temperature viewed from space would have appeared to be 222K but only during the progress of the first convective overturning cycle.

      During that first cycle kinetic energy at the surface was diverted to convective overturning via conduction and was therefore not capable of being radiated to space at the same time.

      Once the first convective overturning cycle completed then the Earth's temperature as viewed from space returned to 255K as per S-B because the kinetic energy being taken up was then simultaneously being returned to the surface.

      Forever afterwards that same 33K of kinetic energy has been locked into the convective overturning cycle and will remain there for so long as the atmosphere remains suspended off the surface against the constant force of gravity.

      Even an 8 year old should be able to grasp such simple concepts.

    2. Direct absorption of incoming solar energy by a layer off the surface of any planet does seek to break the rule but any consequent distortion of the lapse rate slope has to be negated elsewhere in the convective system by distorting the lapse rate slope in an equal and opposite direction.

      The stratosphere on Earth is similar but the distortion of the lapse rate slope by ozone's capacity for absorbing incoming solar energy in the stratosphere is then reversed in our mesosphere.

      Note the definition of 'effective' radiating height. It need not be the same as 'actual' radiating height.

      It can be higher or lower than the point at which radiation is actually sent out to space.

      Is there a region within the vertical atmospheric column of Venus where the effect of absorption by the clouds at TOA is negated ?

  6. HS greenhouse equation 01 09 15
    You don’t refer to CO2 but your physics is standard climate science and wrong.
    Introduction:
    Laws of Physics used:
    1. Conservation of energy
    2. Laws of Motion
    3. Ideal Gas Law (IGL)
    4. Barometic Equation
    I agree with 1 and 2.
    IGL cannot be used for the atmosphere as a whole because T is not the same at each part of the system (not isothermal)
    You also use the hydrostatic equation (HE) without justification
    The Barometric Equation is derived and is wrong in theory and does not work in practice.
    1. Conservation of energy and the ideal gas law
    What you do here is associate conservation of energy which is not controversial with IGL which is.
    You introduce ERL, average effective emission level, not physical. The atmosphere emits at all levels.
    2. Determine the "gravity forcing" upon the atmosphere
    The purpose of this is to convince (yourself?) that gravity is causing weight.
    You say “the weight of the atmosphere over 1 square meter of the surface is 10,500 kilograms”.
    This is not correct. You have calculated the mass over 1 m^2 of surface.
    This calculation was first made by Pascal in 1648.He can be excused but you know weight is not mass.
    Gas molecules do not cause weight because they are moving.
    P(h) = ρgh (7) I don’t accept. Air pressure is not caused by weight. Pressure is in all directions, weight is only down.
    dP = -ρg dh (8)
    Why introduce an infinitesimal? No need, not justified. My suspicion is that knowing pressure falls in an exponential curve the differential is introduced so we can later integrate and get the curve we as looking for. Do you have a better explanation?
    The fatal flaw is here:
    “We can obtain n/V from the ideal gas law: n/V = P/RT (10)”
    BE is derived for isothermal T.

      However the Kinetic Theory of Gas (Bernoulli, 1738) and Statistical Mechanics can be applied to any mass of gas in thermal equilibrium, such as the atmosphere.
      There are not a series of local thermal equilibriums at different heights. There is equilibrium for the whole atmosphere, at least up to the tropopause at 20km. The measured pressure/h is a single continuous smooth curve.

  7. The funny thing is that your theory actually depends on greenhouse gases (GHG). If you would have an atmosphere of pure N2 then only the surface can radiate long wave infrared (IR) or microwave radiation.

    The N2 molecule lacks an internal dipole moment, hence it can not emit or absorb IR or microwave radiation since by fundamental physical laws a fluctuating dipole moment is required for interactions with or emission of photons. It could still emit very high energy light if it was electronically excited I guess but that requires very high temperatures. Green-house gases have the common characteristic of having internal dipole moments (note, it is not a requirement that the molecule has an overall polarity, cf. CO2) so they can absorb or emit low energy photons. These things are explained in fundamental physical chemistry text books like Atkins Physical Chemistry.

    So, for a planet with an atmosphere consisting of only N2 the surface is the only place from which radiation can be emitted at temperatures applicable to planets like earth, because the surface is on the contrary full of molecules or materials with internal dipole moments.

    If N2 was the only gas in earth's atmosphere the surface temperature would have to be the same as that calculated for it without an atmosphere, i.e. 255 K. No gravito-thermal green-house effect then exists, even though the atmosphere has a mass. There would also still be convection due to differential heating at the equator vs. the poles.

    It thus turns out that your gravito-thermal GHE is actually dependent on GHGs. Isn't that ironic.

    1. The gravito-thermal effect is not dependent upon presence of GHGs. I have an upcoming post (as well as prior posts) explaining why a Boltzmann distribution of a pure N2 Earth atmosphere would have a higher surface temperature than the present atmosphere (i.e. GHGs help COOL the atmosphere). Please see these posts (& Feynman) and check back for my upcoming post that clearly proves this using the lapse rate formula alone.

    2. MS, you keep avoiding replying on the specific issues raised in my comments so I will ask you very clearly:

      Do you know that nitrogen gas, i.e. Dinitrogen or N2 molecules, can not absorb or emit long wave radiation such as visible, infrared or microwave light in it's electronic ground state?

      This is an experimentally proven fact and well established theoretically. I am sure you are aware of it, right?

      The Effective Radiative Level (ERL) must therefore by necessity be at the surface for a planet with an atmosphere containing only N2, or any other non-Green-house gas. This is completely independent of the distribution of the gas molecules. It is impossible to radiate energy from higher altitudes in such systems so all energy exchange that occurs between the planet and it's surrounding (sun and space) takes place at the surface. The temperature at the surface then has to be 255 K as determined by the energy balance set by incoming solar energy and outgoing emitted radiation.

      Best wishes

    3. Martin, I'm not avoiding replying on anything. I've already said on this blog a million times N2 and O2 are not IR active gases.

      It is true the ERL height has to be zero in a pure N2 atmosphere. However the equilibrium T with Sun is still fixed at the center of mass & kinetic temperature at the point is 255K.

      My upcoming post will show that the surface T in an earth pure N2 atmosphere would be 25C warmer than the present Ts due to the steeper lapse rate.

    1. Luke you are definitely on the same tracks that I took the only thing you now need is the assumption that gravity and gravitational potential energy must be in continual local and total thermodynamic equilibrium at every point in the atmosphere With "real" or kinetic energy. That's why the lapse rate is simply the ratio of gravitational "-" potential energy (PE)/Cp the great problem of people understanding this simple fact is the pay and did not assume the entire atmosphere always must be inperfect equilibrium with gravity! Therefore both dynamic and kinematic viscosities of the entire kinematic + gravitational PE atmosphere must be always in local + total thermodynamic equilibrium at every point in time and space. Game over for not just 99% of CO2 alarm, but 100%. I can't go into the details yet but I have a very very big news about a breakthrough on this issue I think.

      Regards, and thanks for your interest. Let me know how you are doing and if you have any other questions, thank you.
