Sentences with phrase «from atmospheric radiation»
I'm wondering about what I've recently read about Chemtrails being used to «protect microcircuits from radiation», creating a «web of electrically conducting sheets» or «metallic nets of ultra-fine mesh - spacing» in the stratosphere to protect our semiconductors from atmospheric radiation (solar flares aka coronal ejections).

The whole issue is that any level above what is often called the «effective radiating level» (say, at ~ 255 K on Earth) should start to cool as atmospheric CO2 increases, since the layers above this height are being shielded more strongly from upwelling radiation... except not quite, because convection distributes heating higher than this level, the stratosphere marks the point where convection gives out and there is high static stability.
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).

Trenberth's energy budget schematic appears to claim a quite assymmetrical atmospheric radiation distribution; since he gives an outgoing longwave flux of 235 W / m ^ 2 of which 40 W / m ^ 2 is actually a direct path from the surface; not an atmospheric radiation.
Each higher and cooler layer in turn emits thermal radiation corresponding to its temperature; and much of that also escapes directly to space around the absorption bands of the higher atmosphere layers; and so on; so that the total LWIR emission from the earth should then be a composite of roughly BB spectra but with source temepratures ranging ove the entire surface Temeprature range, as well as the range of atmospheric emitting Temperatures.
