As the atmospheric opacity is increased (e.g., 2xCO2), the physical location of the TAU = 1 level will rise to a higher altitude, but the outgoing flux will still come from the TAU = 1 level since radiation doesn't care about the geometric scale), and the TAU = 1 level will still correspond to the same temperature (since the solar input energy is unchanged).

The increase / decrease of net upward LW flux going from one level to a higher level equals the net cooling / heating of that layer by LW radiation — in equilibrium this must be balanaced by solar heating / cooling + convective / conductive heating / cooling, and those are related to flux variation in height in the same way.

Reviewing the instruments in the pdf was very interesting, the high sensitivity / resolution for the CCD and a lack of shielding in the wake of possible ICME solar flux in the next few years may be worrisome.

«The solar wind, because it is an extended ionized gas of very high electrical conductivity, drags some magnetic flux out of the Sun, thereby filling the heliosphere with the weak interplanetary magnetic field.

A boundary layer with a higher temperature requires the deeper ocean to have a higher temperature for it to sustain the same flux (deltaT) through the boundary layer to the atmosphere (the deeper ocean (< 1 mm) still needs to loose the solar energy or it would start boiling eventually).

Furthermore when solar flux dipped between the 1960s and 80s, a high proportion of Alpine glaciers, as well as glaciers around the world, stopped retreating and many began to advance as seen here in the Alps.

The second discrepancy occurring during the maximum of solar cycle 24 can be explained in terms of the unusually extended polar field reversal, with both northern and southern polar fields being simultaneously positive for over a year, leading to a higher flux of GCR particles at Earth.

This is because the solar wind modulates the flux of high energy particles coming from outside the solar system.

7.4.5 Impact of Cosmic Rays on Aerosols and Clouds 43 44 High solar acti0vity leads to variations in the strength and three - dimensional structure of the heliosphere, 45 which reduces the flux of galactic cosmic rays (GCR) impinging upon the Earth's atmosphere by increasing 46 the deflection of low energy GCR.

Remember the solar wind impacts the Earth with the force of one BigMac w / Fries every second, and even less during a coronal hole [the speed may be high but the density is way down, so the total mass flux is smaller].

The atmosphere is analogous to a flexible lens that is shaped by the density distribution of the gas molecules, of the atmosphere in the space between the sphere holding them, and space; Incoming heat gets collected in many ways and places,, primarily by intermittent solar radiation gets stored, in vast quantities, and slowly but also a barrage of mass and energy fluxes from all directions; that are slowly transported great distances and to higher altitudes mostly by oceanic and atmospheric mass flows.

As a comparison we calculate Ta - V for Venus, which has a higher solar flux since the radius of its orbit is only 60 % that of Earth:

So high solar activity corresponds to low cosmic ray flux and therefore lower cloud formation and higher temperatures.

Quote: «The greenhouse effect theory would have us believe that trace gases in the atmosphere can absorb enough of that immense surface radiative flux to slow it down, which is nonsense, or to radiate enough back to warm the surface to a temperature higher than it is warmed by solar energy.
